Proposal Total: $487,800.00 Page 4 of 4 VA rAlrn TRANSFORMERS TERMS & CONDITIONS The accompanying purchase order ("PO") and these terms collectively constitute the agreement between the parties ("Agreement"). The Agreement becomes binding when VanTran Industries, Inc. ("Seller") provides a written acknowledgment of Buyer's PO. Seller's acceptance of any Buyer PO is expressly conditioned on Buyer's acceptance of the terms and conditions stated herein, and any additional or different terms proposed by Buyer are expressly rejected and shall not become part of the Agreement unless expressly agreed to in writing by Seller. The parties acknowledge that all stenographic or typographic errors in a PO or any other document associated with this Agreement are subject to correction to reflect the intent of the parties. Pricing. Notwithstanding any terms or conditions in Buyer's PO or any other documents, the price for goods shall be as specified in Seller's written quotation or order acknowledgment, whichever is issued last (the "Price"), unless otherwise expressly agreed upon in writing by Seller. Seller is not obligated to honor quotations for goods destined for Federal, State, or Local government unless Buyer notifies Seller at the time of requesting a quotation as these orders frequently involve higher administrative costs. If an agreed -upon shipment date extends beyond 30 days from the originally quoted lead time, or if delays beyond Seller's control prevent production of an order within this period, Seller reserves the right to adjust the Price to reflect any increases in raw material, labor, transportation, or other input costs upon written notice to Buyer. Buyer shall acknowledge the new price by submitting a change order within ten (10) days after receipt of such notification or elect to cancel the applicable order pursuant to the terms of Section 9. 2. Production and Shipment Dates. For orders entered as hold for approval, the time period quoted for lead time commences after approval and release to production and the shipment date will be entered as best available at the time of release. The expectation is that the approval and release to production shall be provided by Buyer within two (2) weeks of receipt of drawings. Should this approval and release to production be delayed by Buyer, Seller reserves the right to adjust the Price to reflect any increases in the production costs and advise Buyer in writing of any such changes in Price. Buyer shall acknowledge the new price by change order submission within (10) days after receipt of such new price notification or elect to cancel the applicable order per the terms of Section 9. If orders go unreleased by Buyer for more than 180 days, Seller may cancel the order pursuant to Section 9. Seller will not pay or be liable for any penalty, either liquidated damages or otherwise, for late delivery or installation. Shipping dates are estimated and are dependent upon many variables including but not limited to prompt receipt of all information and material necessary. The Buyer has the right to change their order if agreed upon by Seller in a signed writing. Should such change(s) alter the price or lead time, Seller shall make a reasonable adjustment of price and/or lead. Changes affecting function or performance of the goods ordered may not be made without Seller's prior written consent. 3. Invoices/Taxes. Buyer shall pay all invoiced amounts due to Seller within 30 days from the date of Seller's invoice. At Seller's sole discretion, payment shall be made via (i) progress payments for orders $200,000 and greater as follows: (a) for liquid - filled transformers, 25% due at time of order acknowledgment, 25% due at time of order release, and 50% due net 30 after shipment with approved line of credit, and (b) for dry transformers, 30% due at time of order acknowledgment and 70% due net 30 after shipment with approved line of credit, (ii) invoiced and paid monthly or (iii) as otherwise provided in the order acknowledgement. Under any payment process, Buyer shall make all payments hereunder by wire transfer or check and in US dollars. Buyer shall pay interest on all late payments at the lesser of the rate of 2.5% per month or the highest rate permissible under applicable law, calculated daily and compounded monthly. In addition, Seller may suspend performance or delay further shipments until all overdue payments, including interest, are paid in full. Buyer shall reimburse Sellerfor all costs incurred in collecting any late payments, including, without limitation, attorneys' fees. Seller's rights under this Section are cumulative and in addition to any other remedies available under this Agreement or at law. Buyer shall not withhold payment of any amounts due and payable as a set-off, counterclaim, or deduction of any kind. The Price is exclusive of all sales, use, and excise taxes, and any other similar taxes and charges of any kind imposed by any governmental authority on any amounts payable by Buyer. Seller shall include, and Buyer shall pay the amount of taxes and charges by government authorities as a line item, when invoiced.

Operation and Maintenance Manual April 2021 www.VanTran.com Page (5 2. General Information: 2.1 Acceptance & Inspection upon Receipt All VanTran transformers are thoroughly tested and rigorously inspected before shipment from the factory to ensure the highest quality. Upon receipt: 1. Thoroughly check all materials against the bill of lading. 2. Locate accessory parts that may have been shipped separately. 3. Carefully check the unit and associated components for any signs of damage caused during shipment. A damaged crate or pallet can be an indication of rough handling; if this condition is found, make a close inspection of the base and radiators (if equipped) and verify no damage has occurred. 4. In the event that significant damage to the unit or any associated equipment is noticed, rejection of the shipment should be made before it is unloaded. In the event of minor damages (nicks, scratches, etc.), carefully inspect the unit and note all damage on the carriers copy of the freight receipt. Note: VanTran ships most units FOB Point of Manufacture, and it is the customer's responsibility to file a claim against the carrier. Note: If acceptance of the transformer is made and damage to the unit is noticed at a later time, it is extremely difficult to file a claim against the carrier. 2.2 Proper Handling & Unloading WARNING: Heavy Equipment. Improper handling can cause severe injury, death, or damage to 1 transformer. Before moving the transformer, read the handling instructions provided in this manual. CAUTION: The transformer weight is shown on the transformer nameplate. Most of the weight is in the tank that holds the core and coil assembly and the insulating liquid. Do not use hoists, cranes, jacks, or forklifts with load capacity less than the transformer weight. WARNING: Transformer accessories such as bushings, leads, arrestors, etc. should never be used as a -- handle to move the transformer. 2.2.1 Moving Transformers Shipped on Pallets Transformers shipped on pallets may be lifted or moved by forklift trucks of proper capacity. When using a forklift, lift with the transformer tank closest to the mast of the forklift since most of the transformer weight is in the tank. Pallet mounted equipment may also be moved by crane or hoist. operation and Maintenance Manual April 2021 www.VanTran.com Page (6 2.2.2 Lifting Transformers by Crane or Hoist Lifting lugs, welded to all transformer tanks, are designed and provided for lifting the complete unit as shipped. VanTran recommends lifting by these lugs as the primary means of movement. Care should be taken to ensure straps, chains, and cables used to lift the units are inspected prior to use. All straps, chains, cables, and lifting devices should be in good working order with sufficient capacity to perform the job intended. Straps, chains, and cables should never be looped from one lug to another to form a continuous loop around the unit or even on one side of the unit. Each chain, strap, or cable should be run only to one lifting lug at a time to prevent loss of control of the unit in the event of a failure with one of the lifting devices. Cable pull angles should never exceed 30° from vertical or damage to the lifting lugs may occur. Spreader beams/bars should be used to hold the cables apart and as close to vertical as possible to minimize the forces on the lifting lugs and lifting devices. 2.2.3 Skidding/Rolling Transformers VanTran transformers are designed to be rolled or skidded into place where accessibility to a crane or other overhead lifting device is limited or not available. If the unit must be rolled, ensure that the area is level, free from obstructions and debris, and is of sufficient strength and thickness to support the load. When rollers are used, use as many as necessary to distribute the weight uniformly. 2.2.4 Using Jacks to Move Transformers Place jacks under the tank base on the open ends of the transformer tank. DO NOT place jacks under radiators, valves, cabinets, or sheet metal components. ALWAYS use at least two jacks per side and raise evenly to prevent warping of the base. 3. Storage: 3.1 Storage for 90 Days or Less All VanTran units have been thoroughly dried at the factory and shipped with oil at the correct level. Transformers should always be stored with oil in place to prevent possible contamination and absorption of moisture. Transformers should be stored in a dry location with no rapid or radical temperature changes. If possible, the transformer should be stored in its permanent location on the foundation which has been prepared for it. If the permanent foundation is not available, it should be stored in its correct upright position on a level foundation capable of withstanding the weight of the unit without deformation. CAUTION: Never store a transformer solely under the jacking steps, on jacks, or on temporary blocking. Never store the transformer on rollers. Never store the transformer in or near standing water or in areas with high moisture, salt levels, or corrosive gases in the air. Operation and Maintenance Manual April 2021 www.VanTran.com Page 17 3.2 Storage for More Than 90 Days All VanTran transformers are shipped with a 2-psi dry nitrogen blanket. During long term storage, it is recommended that this nitrogen blanket be maintained by the addition of a bottle of dry nitrogen, through a regulator, to the transformer tank. If the unit is equipped with anti -condensation heaters in the control cabinets, they should be energized and checked for proper operation. Units with any enclosed air -filled spaces, such as control cabinets and Air Terminal Chambers, should be supplied with an appropriate amount of moisture absorbing desiccant packets. Desiccant should be monitored and replaced in regular maintenance intervals as moisture levels in the storage area dictates. 3.3 Removable Radiators VanTran ships all transformers, when possible, completely assembled and ready for use. In the event that removable radiators are shipped separately to accommodate shipping or space requirements, radiator openings are shipped with temporary protective caps. Ensure these protective caps are tightly sealed before storage. CAUTION: Radiator assemblies should never be stored directly on the ground or in areas in which water �. • could collect near sealed openings. 4. Installation: 4.1 Pre -service Inspection ELECTRICAL SHOCK: Never attempt to change connections on an energized transformer. All installation, maintenance, or repair should be performed by trained, experienced, and qualified personnel only. New transformers, or transformers which are being activated after a period of storage, should be thoroughly inspected before being connected to the power distribution system to identify damage which may have occurred during storage. 1. The transformer exterior should be inspected for nicks, dents, and scratches. Repair damage to weather - resistant finishes promptly. 2. The tank cover and manhole/hand hole cover seals and all gaskets or seals at bushings, gauges, fuses, operating devices, etc., should be inspected for evidence of insulating liquid seepage. Repair leaking or improperly tightened gaskets and seals before the transformer is placed in service. 3. The liquid level inside the tank must be checked (read directly form gauge on transformers equipped with liquid level gauge). 4. Basic electrical tests should be conducted before energizing a transformer which was stored for a period of 90 days or more. Tests include DC insulation Test and Transformer Turns Ratio (TTR). The results of these tests should be verified with the original factory test results to assure they are still within acceptable limits. Operation and Maintenance Manual April 2021 www.VanTran.com Page 18 4.2 Location Consideration The unit should not be placed within 36 inches of any obstructions and ample room should be provided for the removal of cabinets, covers, and inspection hatches. Ample room should be available to perform periodic maintenance inspections and perform repairs as needed. Proper ventilation should be considered to prevent overheating of the unit. For outdoor installations, proper placement of the unit should be away from walls, fences, vegetation, or any other structures that would restrict air movement around the unit. Special precautions should be taken for units installed indoors. Care should be taken to ensure adequate ventilation is provided. Auto -closing vents should be permanently fixed in the open position to prevent unintended closure and accidental overheating of the unit. Fans, blowers, or other means of positive air movement in the space is strongly encouraged to prevent overheating. Indoor Units Recommendation: 1. The size of vents in an enclosed space should be at least 20 ft2 of inlet and 20 ft2 of outlet area per 1000 kVA of unit capacity. 2. High Fire Point Insulating Liquid. 3. Cover Mounted Pressure relief device (PRD) also referred to as Explosion Relief device. CAUTION: Check with local authorities in the intended installation area to verify compliance of any and :. all applicable laws. 4.3 Mounting the Transformer The transformer must be placed on a concrete pad or steel deck of sufficient strength to support the full weight of the unit. The location must be flat and level and prepared to prevent the transformer form tilting beyond two degrees from horizontal. WARNING: Fire Hazard. Non -level installation of transformer can result in fire and cause severe personal injury or death. Prepare transformer installation site such that transformer does not tilt more than two (2.0) degrees from horizontal while the transformer is in service at the site. To maintain full cabinet security, the transformer tank and cabinet base have provisions for installing cleats to secure transformer to pad. If gaps still exist between the cabinet and pad after cleating the cabinet, the installation will not provide the security needed to prevent tampering by the public. Add a permanent mortar seal to fill the gaps. 4.4 External Connection AELECTRICAL SHOCK: Hazardous voltage can cause severe injury, death, or damage to equipment. Ground transformer following industry -accepted safe grounding practices before making other electrical connections. De -energize power distribution wires that will be connected to transformer. Verify that wires are de -energized at the transformer before connecting to transformer. Operation and Maintenance Manual April 2021 www.VanTran.com Page 19 ELECTRICAL SHOCK: Live front parts should such as cables, bushings and other components must be thoroughly tightened and periodically checked to prevent arcing and overheating. Clean bushings and terminals before making Connections. Remove dirt, grease, or foreign material. Contamination can cause failure of the bushings. Cables connected to the transformer terminals are to have sufficient flex to allow normal pad movement due to ground freeze/thaw and settling. Insufficient cable flex may cause premature failure of the bushings. 4.4.1 Ground Connection The transformer tank must be connected to a permanent, low -resistance ground. If the tank is not solidly grounded and the transformer is connected to the power distribution system, then the tank should be regarded as energized. An energized tank is extremely dangerous. Contact with an energized tank can shock, burn, or cause death. VanTran transformers are equipped with at least two ground pads (Fig. 1) or two ground bosses (Fig. 2) depending on transformers size. One is located on the primary side, and the other is located on the secondary side. Fig, Fig. 4.4.2 High Voltage Connection Diagrams and information supplied on the nameplate must be followed for making connection. There are two types of typical high voltage connections. 4.4.3 Live Front Transformer Connections Externally/internally clamped porcelain bushing are normally provided for high voltage connection to Padmount transformers, supplied with eyebolt or spade terminals that are suitable for copper and aluminum conductors. operation and Maintenance Manual April 2021 www.VanTran.com Page 110 4.4.4 Dead Front Transformer Connections Bushing wells or one-piece bushings are normally provided for high voltage connection to Padmount transformers, suitable for elbow connections. 4.4.5 Low Voltage Connection Spade terminals ranging from two holes to twenty holes are typically provided for low voltage connection to Padmount transformers. 5. Accessories: 5.1 Pressure Relief Valve Automatic Pressure relief valve (Fig. 3) is standard on all VanTran transformers and is intended to slowly release pressure to prevent rupture of the transformer. tank. These valves are factory adjusted to vent at 5 ±2 PSI. Normal operation and atmospheric temperature fluctuations cause the oil and components in the tank to naturally expand and contract causing the gas filled head space inside the tank to fluctuate in pressure. CAUTION: Before performing any kind of service that may include, but is not limited to, opening the ! tank or inspection cover, removal of fuses, removal of bushings, opening drain or fill valves, or any other similar operation, the pressure inside the tank must be safely vented manually. CAUTION: Do not open the transformer in the presence of rain, fog, snow, or if there is condensation \` on the exterior components of the unit or when the outside air temperature is higher than the temperature of the unit. Even small amounts of moisture that are allowed to enter the transformer tank can decrease the dielectric strength of the insulating fluid and compromise the integrity of the unit. 115. To manually vent the tank, pull the ring supplied on the valve (Fig. 3) until all pressure or vacuum is relieved. Operation and Maintenance Manual April 2021 www.VanTran.com Page 111 5.2 Fill Plug/Filler Valve (Fluid) with Schrader Valve (Nitrogen) Fill Plug with Schrader Valve (Fig. 4A) or Filler Valve with Schrader Valve (Fig. 413) is provided to facilitate addition of dielectric fluid and Nitrogen to the tank. Note: The transformer departs factory with 2-3 PSI of positive nitrogen pressure (blanket) at ambient temperature above the dielectric fluid column. m 5.3 Drain Valve & Fluid Sampler a / • r The Drain Valve and Fluid Sampler (Fig. 5) is provided to facilitate sampling of the dielectric fluid for testing and other purposes. The valve is also equipped with a plug ranging from %" to 2" to provide means of draining the dielectric fluid. Sampling is usually performed on the side of the valve without the need to remove the end plug. 0 Operation and Maintenance Manual April 2021 www.VanTran.com Page 112 5.4 Liquid Level Gauge A liquid level gauge (Fig. 6) is supplied to indicate the amount of dielectric fluid in the transformer tank. The gauge consists of a float arm inside the tank magnetically coupled to the indicator needle inside the gauge. The magnetic coupling maintains a liquid tight separation between the interior oil and the outside to minimize potential leaks. On LIQUID 65 C LEVEL U' 0 VanTran utilizes several different brands and models of liquid level gauges depending on the application. Transformers can be supplied with a standard gauge or more sophisticated models with either one or two SPDT (Single Pole Double Throw) alarm contacts to facilitate external monitoring. Liquid Levels may vary under normal operation according to temperature and pressure. The 25' C mark is only a reference fluid level at 250 C. Note: For wiring and other information, please refer to the schematics included in the submittal drawings. Operation and Maintenance Manual April 2021 www.VanTran.com Page 113 5.5 Temperature Gauge The temperature gauge (Fig. 7) is supplied to indicate the dielectric fluid temperature in degrees centigrade at the top of the oil column. The gauge consists of two needles (one white and one red). The white needle is the current oil temperature of the unit, while the red needle is a resettable maximum indicator. As the temperature of the oil rises, the white needle pushes the red needle higher with it. If the temperature of the oil declines the white needle follows and goes down with temperature while the red needle remains at the highest temperature reached and acts as a recorder to indicate the highest temperature achieved by the unit. The red needle (maximum indicator) can be reset by turning the knob on the front of the gauge face. The temperature gauge consists of a long thermocouple that extends into the tank inside a protective thermocouple well. The isolation between the thermocouple and the dielectric fluid facilities the removal and replacement of the gauge without draining down the dielectric fluid. j`O�O�aDDI, O O d Q 0 IIf�V e 0 The temperature gauge can be equipped with either one or two SPDT alarm contacts for remote monitoring or fan control. These alarm contacts are factory set but can be adjusted if desired. To adjust the contacts, remove the face of the gauge. Look toward the center of the gauge for a small Allen head set screw. Loosen this set screw and manually move the contacts (red indicators toward the outer edge of the dial) to the desired temperature settings. Gently retighten the set screw and replace gauge face. Note: For wiring and other information, please refer to the schematics included in the submittal drawings. Operation and Maintenance Manual April 2021 www.VanTran.com Page 114 5.6 Pressure Vacuum Gauge The pressure vacuum gauge (Fig. 8) indicates whether the head space pressure inside the tank is positive, negative, or neutral. The pressure inside the tank will vary depending on the load of the unit, temperature of the oil and ambient temperature outside. As the oil temperature rises, the pressure inside the tank also rises. As the temperature falls, the pressure falls. It is common for a transformer to have either a positive pressure or a negative pressure. Do not be alarmed by a consistent negative pressure (for example, if it is winter in Wisconsin, it will likely be negative for the duration of the season). However, if the gauge consistently reads zero and does not appear to be changing with environmental or load conditions, this may be an indication of a leak and may need attention. Visually inspect the unit for any signs of a leak or damaged seal. I 5 10 10 VAC PRESS Mr., PSIG Fig. The pressure/vacuum gauge can also be equipped with SPDT alarm contacts (by adding a separate pressure alarm switch) for remote monitoring of positive and negative pressures. When requested, the pressure/vacuum gauge can also be equipped with a bleeder or regulator; when used in conjunction with an external nitrogen supply, positive pressure can be maintained inside the tank (2.5 to 3.0 PSI) The regulator is also equipped with a fitting and valve to take gas samples. Operation and Maintenance Manual April 2021 www.VanTran.com Page 115 5.7 Fault Pressure Relief Device (FPRD) Also commonly referred to as an Explosion Relief Device (Fig. 9), this device facilitates the rapid release of gas pressure in the event of an internal fault. This device should not be confused with a standard Automatic Pressure Relief Valve as shown in (Fig. 3), which only releases pressure slowly to account for thermal expansion and contraction. A PRD is cover mounted and equipped with a spring -loaded diaphragm that is factory set to open at a predetermined pressure level (Typically 10 psi). After the tank pressure returns to normal the Diaphragm will close and reseal the unit. The FPRD is equipped with an indicator (yellow button on top) that will protrude vertically after an event until it is reset. The FPRD can also be supplied with SPDT alarm contacts for remote monitoring.

De -energize transformer from a remote upstream source before servicing or operating surge arresters or disconnect switches. Check that all transformer terminals and bushings have zero voltage. Ground transformer following industry accepted safe grounding practices. CAUTION: Excessive test voltage can damage surge arresters. Disconnect surge arresters before running impulse or applied potential tests on the transformer. Surge Arresters (Fig. 20A & 2013) are provided optionally in Padmount transformers to protect equipment and cables from overvoltage surges. During steady state conditions, line -to -ground voltage is applied continuously across the arrester terminals. When surges occur, the arrester immediately limits the overvoltage to the required protective level by conducting the surge current to ground. Upon passage of the surge, the arrester returns to its initial state, conducting minimal leakage current.

The Inertaire® nitrogen gas control system includes all the pressure regulating components and controls which are needed to maintain a positive pressure, nitrogen atmosphere in the gas space of a transformer. When gas space pressure falls below the low-pressure limit, the Inertaire® system automatically feeds fresh nitrogen into the transformer gas space until the gas space pressure is restored to a value above the low-pressure limit. When the gas space pressure exceeds the high-pressure limit, the Inertaire® system automatically vents excess pressure to atmosphere through the pressure relief unit. Fig. 24 6.9 Radiator Functional Operation When the transformer is under loading condition, the transformer windings will be heated enormously, and rises the temperature of transformer oil. That heat must be reduced under allowable value otherwise the transformer may me damaged due over heating. The Radiators installed to the transformer reduces the heat by accelerating the transformer oil. Under loaded condition, warm oil increases in volume and comes to the upper portion of the main tank. Then this oil enters in the radiator through top valve and cools down by dissipating heat through the thin radiator wall. This cold oil comes back to the main tank through the bottom radiator valve. This cycle is repeated continuously till the load is connected to the transformer. Thus, it plays a vital role in increasing loading capacity of an electrical transformer.

Factory Testing: CAUTION: The information below is not intended to be as a guideline for testing transformers. Please refer to IEE/ANSI C57.12.90-2006 and ANSI/NETA ATS-2009 for more details. 8.1 Routine Tests 8.1.1 Ratio The turn ratio of a transformer is the ratio of the number of turns in the high voltage winding to that in the low voltage winding. When the transformer has taps, the turn ratio shall be determined for all taps and for the full winding. Note: The ratio test can also be used to test polarity, phase relation, and phase sequence. 8.1.2 Winding Resistance Resistance measurements are of fundamental importance for the calculation of the I211 component of conductor losses and calculation of winding temperatures at the end of a temperature rise test. 8.1.3 No Load & Excitation Current No-load (Excitation) losses are losses that are incident to the excitation of the transformer. No-load losses include core loss, dielectric loss, conductor loss in the winding due to excitation current, and conductor loss due to circulating current in parallel windings. These losses change with the excitation voltage. Excitation current (no-load current) is the current that flows in any winding used to excite the transformer when all other windings are open -circuited. It is generally expressed in percent of the rated current of the winding in which it is measured. The no-load losses consist primarily of the core loss in the transformer core, which is a function of the magnitude, frequency, and waveform of the impressed voltage. No-load losses also vary with temperature and are particularly sensitive to differences in waveform; therefore, no-load loss measurements will vary markedly with the waveform of the test voltage. 8.1.4 Load Losses & Impedance Voltage The load losses of a transformer are losses incident to a specified load carried by the transformer. Load losses include 12R loss in the windings due to load current and stray losses due to eddy currents induced by leakage flux in the windings, core clamps, magnetic shields, tank walls, and other conducting parts. The impedance voltage of a transformer is the voltage required to circulate rated current through one of two specified windings when the other winding is short-circuited, with the windings connected as for rated voltage operation. Impedance voltage is usually expressed in per unit or in percent of the rated voltage of the winding across which the voltage is applied and measured. Operation and Maintenance Manual April 2021 www.VanTran.com Page 135 8.1.5 Dielectric Strength The dielectric test of the transformer is intended to check the ability of main insulation to earth, inter turn and line end insulation to earth. It is generally performed in two different steps, likewise, separate applied voltage withstands test (Hi -Pot) and induced voltage withstand test. 8.2 Special/Design Tests 8.2.1 Insulation Power Factor (Tan S) The insulation power factor is the ratio of the power dissipated in the insulation in watts to the product of The effective voltage and current in volt-amperes when tested under a sinusoidal voltage and prescribed conditions. 8.2.2 Insulation Resistance Insulation resistance tests are made to determine the insulation resistance from individual windings to ground or between individual windings. Insulation resistance tests are commonly measured in mega ohms or may be calculated from measurements of applied voltage and leakage current. 8.2.3 Temperature Rise A temperature -rise test is defined as a test to determine the temperature rise above ambient of one or more of the transformer's windings, as measured at the terminals. The result for a given terminal pair or winding is the average value of the temperature of the entire circuit; it is not the temperature at any given point in a specific winding. The term average temperature rise refers to the value determined by measurements on a given terminal pair of the winding. It does not refer to the arithmetic average of results determined from different terminal pairs of the transformer. 8.2.4 Lightning Impulse Lightning impulse tests shall consist of and be applied in the following order: one reduced full wave, two chopped waves, and one full wave. The time interval between applications of the last chopped wave and the final full wave should be minimized without intentional delays, to avoid recovery of dielectric strength if a failure were to occur prior to the final full wave. Impulse tests shall be made without excitation. Note: Please refer to IEEE Standard C57.98-2011. Operation and Maintenance Manual April 2021 www.VanTran.com Page 136 8.2.5 Audible Sound Level Audible sound from transformers originates principally in the transformer core and transmits through the dielectric fluid and/or structural supports, to the outer shell and/or other solid surface, where it radiates as airborne sound. In some situations, the windings may be a noise source under rated load conditions, but this noise is not included in this standard. The frequency spectra of the audible sound consist primarily of the even harmonics of the power frequency; thus, for a 60 Hz power system, the audible sound spectra consist of tones at 120 Hz, 240 Hz, 360 Hz, 480 Hz, etc. The audible sound also contains the noise emitted by any dielectric fluid mechanical cooling system. Mechanical cooler sound consists of broadband fan noise, plus discrete tones at the fan blade passage frequency and its harmonics. 9. Maintenance: 9.1 Spare Parts VanTran specializes in manufacturing custom transformers and makes only limited quantities of any one design. Replacement parts are best handled on a case -by -case basis. Should additional or replacement parts be necessary for any VanTran transformer, please contact the factory and provide all available nameplate data. 9.2 Routine Inspection Routine inspection of the exterior of the unit should be performed periodically. The inspection interval should take the environmental conditions of the site into consideration. Salty, damp, or otherwise corrosive environments will require shorter inspection intervals than dry/mild conditions. Periodically check between the radiators (if equipped) for debris and obstructions. Ensure that the unit is getting adequate airflow and that brush, overgrowth, or surrounding equipment is not impeding proper airflow. If the unit is equipped with forced air cooling, manually cycle the fans using the switch in the control panel to ensure proper operation. Clean any dirt or buildup away from the base and cabinet areas to prevent premature rust and deterioration. During an external inspection, check the paint for signs of deterioration, including cracked/chipping paint and rust. If paint damage or deterioration has occurred, touch-up or repaint the exterior of the unit as soon as possible to prevent further degradation. VanTran uses several different painting processes depending on the application. An inquiry to the factory, with the serial number of the unit, will determine the type and compatibility of the touch-up paint required. Operation and Maintenance Manual April 2021 www.VanTran.com Page 137 Gauges should be checked regularly for proper operation. The temperature gauge should fluctuate with load conditions and ambient temperature. However, the gauge should never read over the design value on the nameplate plus the average daily ambient temperature. For example, if it is a 25*C day and it has a 650C rating on the nameplate it should not read over 90'C on the gauge. The liquid level gauge will also fluctuate slightly with temperature and loading but a steady drop may indicate a leak and should be addressed. The pressure/vacuum gauge will vary with temperature as well but should never register zero for prolong periods of time (another indication of a leak). 9.3 Dielectric Fluid Sampling Dielectric fluid samples should be taken at least on an annual basis and analyzed by DGA (Dissolved Gas Analysis). Routine DGA testing is one of the best methods of determining the "Health" of a transformer.

For maximum efficiency, cores are precisely stacked, virtually eliminating gaps in the corner joints. Five -legged wound core or shell -type triplex designs are used for wye-wye connected transformers, and other special transformer designs. Cores are manufactured with precision cut, burr -free, grain -oriented silicon steel. Many grades of core steel are available for optimizing core loss efficiency. Coils Pad -mounted transformers feature a rectangular coil configuration with wire -wound, high -voltage primaries and sheet -wound secondaries. The design minimizes axial stress developed by short circuits and provides for magnetic balancing of tap connections. Coils are wound using the highest quality winding machines provid- ing exacting tension control and conductor placement for superior short-circuit strength and maximum efficiency. Extra mechanical strength is provided by diamond pattern, epoxy - coated paper insulation, used throughout the coil, with additional epoxy at heavy stress points. The diamond pattern distribution of the epoxy and carefully arranged ducts, provide a network of passages through which cooling fluid can freely circulate. Coil assemblies are heat -cured under calculated hydraulic pressure to ensure performance against short-circuit forces. Core and coil assemblies Pad -mounted transformer core and coil assemblies are braced with heavy steel ends to prevent the rectangular coil from distorting under short-circuit conditions. Plates are clamped in place using presses, and welded or bolted to form a solid core and coil assembly. Core and coil assemblies exceed ANSI® and IEEE® requirements for short-circuit performance. Due to the rigidity of the design, impedance shift after short-circuit is comparable to that of circular wound assemblies. Tanks Transformer tanks are designed for high strength and ease of handling, installation, and maintenance. Tanks are welded using precision -cut, hot rolled, pickled and oiled steel. They are sealed to protect the insulating fluid and other internal components. Transformer tanks are pressure -tested to withstand 7 psig without permanent distortion and 15 psig without rupture. Tank finish An advanced multi -stage finishing process exceeds IEEE Std C57.12.28TM-2014 standards. The eight -stage pre-treatment process assures coating adhesion and retards corrosion. It converts tank surfaces to a nonmetallic, water insoluble iron phosphate coating. The paint method consists of two distinct layers of paint. The first is an epoxy primer (E-coat) layer which provides a barrier against moisture, salt and corrosives. The two -component urethane final coat seals and adds ultraviolet protection. Vacuum processing Transformers are dried and filled with filtered insulating fluid under vacuum, while secondary windings are energized. Coils are heated to drive out moisture, ensuring maximum penetration of fluid into the coil insulation system. Insulating fluid Eaton's Cooper Power series transformers are available with electrical -grade mineral insulating oil or EnvirotempTM FR3TM fluid. The highly refined fluids are tested and degassed to assure a chemically inert product with minimal acid ions. Special additives minimize oxygen absorption and inhibit oxidation. To ensure high dielectric strength, the fluid is re -tested for dryness and dielectric strength, refiltered, heated, dried, and stored under vacuum before being added to the completed transformer. Eaton's Cooper Power series transformers filled with EnvirotempTM FR3TM fluid enjoy unique fire safety, environmental, electrical, and chemical advantages, including insulation life extend- ing properties. A bio-based, sustainable, natural ester dielectric coolant, EnvirotempTM FR3TM fluid quickly and thoroughly biodegrades in the environment and is non -toxic per acute aquatic and oral toxicity tests. Building for Environmental and Economic Sustainability (BEES) total life cycle assessment software, utilized by the US Dept. of Commerce, reports its overall environmental performance impact score at 1/4th that reported for mineral oil. EnvirotempTM FR3TM fluid has also earned the EPA Environmental Technology Verification of transformer materials. With a fire point of 360 °C, EnvirotempTM FR3TM fluid is FM Approved® and Underwriters Laboratories (UL®) Classified "Less - Flammable" per NEC® Article 450-23, fitting the definition of a Listed Product per NEC®. Figure 8. VFI transformer with visible break. Pad -mounted VFI transformer Eaton's Cooper Power series VFI transformer combines a conventional distribution transformer with the proven Vacuum Fault Interrupter (VFI). This combination provides both voltage transformation and transformer over current protection in one space saving and money saving package. The pad -mounted VFI transformer protects the transformer and provides proper coordination with upstream protective devices. When a transformer fault or overload condition occurs, the VFI breaker trips and isolates the transformer. The three-phase VFI breaker has independent single-phase initiation, but is three-phase mechanically gang -tripped. A trip signal on any phase will open all three phases. This feature eliminates single -phas- ing of three phase loads. It also enables the VFI breaker to be used as a three-phase load break switch. Due to the resettable characteristics of the VFI breaker, restoring three-phase service is faster and easier. The sealed visible break window and switch is an option that can be installed to provide visible break contact. This feature provides enhanced safety and allows an operator to see if the loadbreak switch contacts are in an open or closed position before performing maintenance. www.eaton.com/cooperpowerseries Catalog Data CA202003EN Effective July 2015 Three-phase pad -mounted compartmental type transformer EnvirotranTM FM Approved special protection transformer Eaton's Cooper Power series EnvirotranTM transformer is FM Approved and suitable for indoor locations. Factory Mutual Research Corporation's (FMRC) approval of the Envirotran transformer line makes it easy to comply with and verify compliance with Section 450.23, 2008 NEC, Less -Flammable Liquid -Filled Transformer Requirements for both indoor and outdoor locations. Envirotran FM Approved transformers offer the user the benefit of a transformer that can be easily specified to comply with NEC, and makes FM Safety Data Sheet compliance simpler, while also providing maximum safety and flexibility for both indoor and outdoor installations. Because the "FM Approved" logo is readily visible on the transformer and its nameplate, NEC compliance is now easily verifiable by the inspector. Envirotran FM Approved transformers are manufactured under strict compliance with FMRC Standard 3990 and are filled with FM Approved EnvirotempTM FR3TM fluid, a fire-resistant dielectric coolant. <19> APPROVED Special application transformers Data Center transformer With focus rapidly shifting from simply maximizing uptime and supporting demand to improving energy utilization, the data center industry is continually looking for methods to increase its energy efficiency and reliability. Utilizing cutting edge technology, Eaton's Cooper Power series Hardened Data Center (HDC) transformers are the solution. Designed with special attention given to surge protection, HDC liquid -filled transformers provide superior performance under the harshest electrical environments. Contrary to traditional dry -type units, HDC transformers provide unsurpassed reliability, overloadability, operational life, efficiency, thermal loading and installed footprint. These units have reliably served more than 100 MW of critical data center capacity for a total of more than 6,000,000 hours without any reported downtime caused by a thermal or short-circuit coil failure. The top priority in data center operations is uninterrupted service. Envirotran HDC transformers from Eaton, having substantially higher levels of insulation, are less susceptible to voltage surges. Eaton has experienced zero failures due to switching transients. The ANSI® and IEEE® standard impulse withstand ratings are higher for liquid -filled transformers, making them less susceptible to insulation failure. The Envirotran HDC transformer provides ultimate protection by increasing the BIL rating one level higher than standard liquid -filled transformer ratings. The cooling system of liquid -filled transformers provides better protection from severe overloads —overloads that can lead to significant loss of life or failure. Data center design typically includes multiple layers of redundancy, ensuring maximum uptime for the critical IT load. When best in class transformer manufacturing lead times are typically weeks, not days, an unexpected transformer failure will adversely affect the facility's reliability and profitability. Therefore, the ability to determine the electrical and mechanical health of a transformer can reduce the probability of costly, unplanned downtime. Routine diagnostic tests, including key fluid properties and dissolved gas analysis (DGA), can help determine the health of a liquid -filled transformer. Although sampling is not required for safe operation, it will provide the user with valuable information, leading to scheduled repair or replacement, and minimizing the duration and expense of an outage. With a dry -type transformer, there is no reliable way to measure the health or likelihood of an impending failure. www.eaton.com/cooperpowerseries Solar transformer As a result of the increasing number of states that are adopting aggressive Renewable & Alternative Energy Portfolio Standards, the solar energy market is growing —nearly doubling year over year. Eaton, a key innovator and supplier in this expanding market, is proud to offer its Cooper Power series Envirotran transformers specifically designed for Solar Photovoltaic medium -voltage applications. Eaton is working with top solar photovoltaic developers, integrators and inverter manufacturers to evolve the industry and change the way we distribute power. In accordance with this progressive stance, every Envirotran Solar transformer is filled with non -toxic, biodegradable EnvirotempTM FR3TM dielectric fluid, made from renewable seed oils. On top of its biodegradability, EnvirotempTM FR3TM fluid substantially extends the life of the transformer insulation, saving valuable resources. What better way to distribute green power than to use a green transformer. In fact, delaying conversion to Envirotran transformers places the burden of today's environmental issues onto tomorrow's generations. Eaton can help you create a customized transformer, based on site specific characteristics including: temperature profile, site altitude, solar profile and required system life. Some of the benefits gained from this custom rating include: • Reduction in core losses • Improved payback on investment • Reduction in footprint • Improved fire safety • Reduced environmental impact For the solar photovoltaic industry, Eaton is offering standard step up transformers and dual secondary designs, including 4-winding, 3-winding (Low -High -Low) and 3-winding (Low -Low -High) designs. Wind transformer Eaton is offering custom designs for renewable energy power generation. Eaton manufactures its Cooper Power series Generator Step -Up (GSU) transformers for installation at the base of every wind turbine. Additionally, grounding transformers are available for wind power generation. DOE efficiency The United States Department of Energy (DOE) has mandated efficiency values for most liquid type, medium voltage transformers. As a result, all applicable Eaton's Cooper Power series transformers 2500 kVA and below conform to efficiency levels as specified in the DOE ruling "10 CFR Part 431 Energy Conservation Program': Underwriters Laboratories® (UL®) Listed and Labeled/ Classified The Envirotran transformer from Eaton can be specified as UL® Listed & Labeled, and/or UL® Classified. Underwriters Laboratories (UL®) listing is a verification of the design and construction of the transformer to the ANSI® and IEEE® standards. UL® listing generally is the most efficient, cost-effective solution for complying with relevant state and local electrical codes. UL® Combination Classification/Listing is another way in which to comply with Section 450.23, 2008 NEC® requirements. This combines the UL® listed transformer with a UL® Classified Less -Flammable Liquid and complies with the use restrictions found within the liquid Classification. c Dus LISTED Three-phase pad -mounted compartmental type transformer Catalog Data CA202003EN Effective July 2015 K-Factor transformer With a drastic increase in the use of ferromagnetic devices, arcing devices, and electric power converters, higher frequency loads have increased significantly. This harmonic loading has the potential to generate higher heat levels within a transformer's windings and leads by as much as 300%. Harmonic loading has the potential to induce premature failure in standard -design distribution transformers. In addition to standard UL® "K-Factor" ratings, transformers can be designed to customer -provided specifications detailing precise loading scenarios. Onsite measurements of magnitude and frequency, alongside harmonic analysis of the connected load can be performed by Eaton engineers or a third party consultant. These field measurements are used to determine exact customer needs and outline the transformer specifications. Eaton will design harmonic -resistant transformers that will be subjected to the unique harmonic loads. These units are designed to maintain normal temperature rise under harmonic, full -load conditions. Standard UL® "K-Factor" designs can result in unnecessary costs when the "next -highest" K-Factor must be selected for a calculated design factor. To save the customer these unnecessary costs, Eaton can design the transformer to the specific harmonic spectrum used in the application. Eaton's Cooper Power series K-factor transformers are filled with mineral oil or EnvirotempTM FR3TM fluid and enjoy the added benefits of dielectric cooling such as higher efficiencies than dry -type transformers. Modulation transformer Bundled with an Outboard Modulation Unit (OMU) and a Control and Receiving Unit (CRU), a Modulation Transformer Unit (MTU) is designed to remotely achieve two way communication. The use of an MTU reduces travel time and expense versus tra- ditional meter reading performed by high voltage electricians. Additionally, with MTU it is possible to manage and evaluate energy consumption data, providing reduced metering costs and fewer ten- ant complaints. An MTU utilizes existing utility infrastructure, therefore eliminating the need to engineer and construct a dedicated communication network. Figure 9. Modular transformer. Inverter/rectifier bridge Eaton complements its range of applications for transformers by offering dual winding designs. These designs are intended for connection to 12-pulse rectifier bridges.

Superior paint performance Protecting transformers from nature's elements worldwide, Eaton's E-coat system provides unrivaled transformer paint life, and exceeds IEEE Std C57.12.28TM-2014 and IEEE Std C57.12.29TM-2005 standards. In addition to the outside of the unit, each transformer receives a gray E-coat covering in the interior of the tank and cabinet, providing superior rust resistance and greater visibility during service. If the wide range of standard paint selections does not suit the cus- tomer's needs, Eaton will customize the paint color to meet their requirements. Rectangular coil design Eaton utilizes a rectangular coil design. This winding technique results in a smaller overall unit footprint as well as reducing the transformer weight. The smaller unit size does not hinder the transformer performance in the least. Units have proven short circuit withstand capabilities up to 10 MVA. Testing Eaton performs routing testing on each transformer manufactured including the following tests: • Insulation Power Factor: This test verifies that vacuum processing has thoroughly dried the insulation system to required limits. • Ratio, Polarity, and Phase Relation: Assures correct winding ratios and tap voltages; checks insulation of HV and LV circuits. Checks entire insulation system to verify all live -to -ground clearances. • Resistance: This test verifies the integrity of internal high -voltage and low -voltage connections; provides data for loss upgrade calculations. • Routine Impulse Tests: The most severe test, simulating a lightning surge. Applies one reduced wave and one full wave to verify the BIL rating. • Applied Potential: Applied to both high -voltage and low -voltage windings, this test stresses the entire insulation system to verify all live -to -ground clearances. • Induced Potential: 3.46 times normal plus 1000 volts for reduced neutral designs. • Loss Test: These design verification tests are conducted to assure that guaranteed loss values are met and that test values are www.eaton.com/cooperpowerseries Catalog Data CA202003EN Three-phase pad -mounted compartmental type transformer Effective July 2015 within design tolerances. Tests include no-load loss and excitation current along with impedance voltage and load loss. • Leak Test: Pressurizing the tank to 7 psig assures a complete seal, with no weld or gasket leaks, to eliminate the possibility of moisture infiltration or fluid oxidation. Design performance tests The design performance tests include the following: Temperature Rise: Our automated heat run facility ensures that any design changes meet ANSI® and IEEE® temperature rise criteria. • Audible Sound Level: Ensures compliance with NEMA® requirements. • Lightning Impulse: To assure superior dielectric performance, this test consists of one reduced wave, two chopped waves and one full wave in sequence, precisely simulating the harshest conditions.

Prolonged overload operation will measurably shorten the projected service life of a mineral oil -filled transformer. Eaton's Cooper Power' series PEAKTM' transformers may help to extend insulation life and can be operated at higher capacities than traditional units while still exceeding ANSI® standard insulation life. Introduction Eaton provides installation and maintenance instructions for its Cooper Powerrm series transformers in Service Information MN202001 EN. These transformers are designed for installation on three-phase underground systems. All units are constructed for weather -exposed mounting on a concrete pad with high- and low -voltage cable entering the operating compartments through an opening in the pad. Read this manual first Read and understand the contents of this manual and follow all locally approved procedures and safety practices before installing or operating this equipment. Additional information These instructions are not intended to cover all details or variations in the equipment, procedures, or process described, nor to provide directions for meeting every possible contingency during installation, operation, or maintenance. For additional information, contact your Eaton representative. Acceptance and initial inspection Receiving Inspection It is important that a thorough inspection of the transformer be made before it is unloaded from the carrier. 1. Ensure that all parts listed on the bill of lading are present. 2. Before unloading the transformer, inspect for signs of damage or mishandling. Locate accessory parts that may have been shipped separately. If damage is detected or shortages are noticed, write a brief description on the freight bill. Normally, the transformer is shipped FOB point of manufacture, and it is the customer's responsibility to file a claim against the carrier. If the transformer was shipped FOB destination, notify your Eaton representative. He or she will, with the inspector's report, take the necessary steps to file a claim against the carrier. A WARNING Heavy Equipment. Improper handling can cause severe injury, death, or damage to transformer. Before moving the transformer, read the handling instructions provided in this manual. Handling Special procedures must be followed when handling transformer in ambient temperatures below -20 'C. Contact your Eaton representative for further instructions. Failure to follow special handling procedures may cause premature failure of transformer and its components. Transformer weight The transformer weight is shown on the transformer nameplate. Most of the weight in a pad -mounted transformer assembly is in the main tank that holds the core and coil assembly and the insulating liquid. Moving transformers shipped on pallets Transformers shipped on pallets may be lifted or moved by forklift trucks of proper capacity. When using a forklift, lift with the transformer tank closest to the mast of the forklift since most of the transformer weight is in the tank. Pallet - mounted equipment may also be moved by crane or hoist. Lifting transformers by crane or hoist Check the weight of the transformer and the capacity and condition of all hoisting or lifting equipment. Do not use worn, frayed or damaged cables or slings. Do not use hoisting machinery with load capacity less than the weight of the transformer. Improper use of hoist or jack could seriously damage the transformer or its attachments or cause serious personal injury. For unloading, lifting lugs are provided near the top of the transformer tank. Lifting chain or cable angles should not be over 300 from vertical. Otherwise, spreaders should be used to hold the lifting cables apart to avoid any bending of the structure or lifting lugs. Do not attempt to lift the transformer by placing a continuous loop of chain or cable around the unit or lifting lugs. This can damage the transformer and can cause accidents resulting in serious personal injury. If the transformer cannot be lifted by crane, it may be skidded or moved by rollers. Using jacks Place jacks under the tank base on the open ends of the transformer tank. Jacking pads are provided for transformers with bases greater than 6" Do not place jacks under radiators or terminal compartment frames. When jacking a transformer for insertion of rollers underneath it, ensure that four jacks are used and that two adjacent corners are raised simultaneously and evenly to avoid warping the base. When using rollers, use as many as necessary to distribute the weight uniformly. Do not attach pulling lines to moldings or other sheet metal parts of the transformer. Three-phase pad -mounted compartmental type installation and maintenance instructions MN202001EN August 2015 Storage Transformers that will not be placed in service immediately should be stored with terminal compartment doors closed and sealed to prevent damage to bushings or other attachments. Installation Installation location The transformer must be located to meet applicable fire codes. For indoor installations, the installation location must meet the requirements of the National Electrical Code (NEC®) with sufficient space requirements and proper over - current protection as specified by the listing body that has jurisdiction over the installation. These pad -mounted transformers are built to operate at altitudes up to 3300 feet at 30 °C average and 40 °C maximum ambient, unless otherwise specified. Before operating a standard transformer at higher altitudes, contact your Eaton representative. Mounting the transformer The transformer should be mounted on a level concrete pad. The pad should be strong enough to support the weight of the transformer. The site must be adequately prepared to prevent the transformer from tilting beyond two degrees from horizontal. A WARNING Fire Hazard. Non -level installation of transformer can result in fire and cause severe personal injury or death. Prepare transformer installation site such that transformer does not tilt more than two (2.0) degrees from horizontal while the transformer is in service at the site. Tilting beyond two degrees may cause internal components to come out of the oil and/or cables to mechanically stress the bushings and bushing gaskets. Excessive tilt (beyond two degrees) can result in a lower dielectric strength for the transformer than the basic insulation level (BIL) listed on the nameplate. Reduced BIL can result in an internal dielectric breakdown with a risk of explosion, tank rupture, or fire. To maintain full cabinet security, the transformer tank and cabinet base have provisions for installing cleats to secure transformer to pad. If gaps still exist between the cabinet and pad after cleating the cabinet, the installation will not provide the security needed to prevent tampering by the public. Add a permanent mortar seal to fill the gaps. Quality standards ISO 9001 certified quality management system Pre -service inspection (exterior) New transformers, or transformers which are being activated after a period of storage, should be thoroughly inspected before being connected to the power distribution system to identify damage which may have occurred during storage. 1. The transformer exterior should be inspected for nicks, dents, and scratches. Repair damage to weather - resistant finishes promptly. 2. The tank cover and manhole/handhole cover seals and all gaskets or seals at bushings, gauges, fuses, operating devices, etc., should be inspected for evidence of insulating liquid seepage. Repair leaking or improperly tightened gaskets and seals before the transformer is placed in service. 3. Under normal conditions, the transformer leaves the factory with a slight positive pressure in the tank over the oil. However, due to changes in atmospheric conditions, the unit may arrive under vacuum (negative pressure). This is itself is not cause for concern, however continued absence of either negative or positive pressure may indicate a leak at a gasket seal or tank seam, and require further investigation. To leak test transformer, remove the pressure relief valve (see Figure 1) and pressurize the headspace to ensure that there are no leaks. The test pressure should not exceed 7 psig. The established pressure should be maintained for at least four hours to ensure that all the seals are proper. Figure 1. Pressure relief valve. Three-phase pad -mounted compartmental type installation and maintenance instructions MN202001EN August 2015 A CAUTION Elevated Pressure. Can cause severe personal injury. Do not remove liquid level plug (see Figure 2) before venting transformer to zero pressure. Pull ring on pressure relief valve to relieve pressure. Figure 2. Liquid level plug. The liquid level inside the tank must be checked (see Insulating Liquid Maintenance section of this manual). On transformers equipped with a liquid level gauge, the liquid level may be read directly from the gauge. On transformers that are not gauge equipped, the tank liquid level must be determined by removing the liquid level plug (see Figure 2). At 25 °C liquid temperature, the liquid level should be at the bottom edge of the liquid level plug hole. If the tank temperature is greater than ambient air tem- perature, the transformer tank must be vented to zero pressure before the liquid level plug is removed. Failure to do so may cause hot oil to be sprayed from the plug hole and may result in severe personal injury. A WARNING Fire Hazard. Energizing transformer in ambient temperatures below -20 °C can result in fire and cause severe personal injury or death. Contact your Eaton representative for further instructions on energizing transformer in ambient temperatures below -20 °C. Special procedures must be followed when energizing a transformer in ambient temperatures below -20 °C. Contact your Eaton representative for further instructions. Failure to follow special start- up procedures may cause premature failure of the transformer and its components. Also, note warning and caution statements in Switches and Protective Devices section of this manual for further precautions when operating under -oil loadbreak accessories in insulating liquid temperatures below 0 'C. Pre -service inspection (interior) Pre -service interior inspection may not be required if exterior inspection reveals no evidence of damage. CAUTION Before opening the transformer tank for Pre -Service Inspection, read the Insulating Liquid Maintenance section in this manual.This section explains safety precautions that should be taken and gives instructions on how to prevent insulating liquid contamination. If interior inspection is required, the transformer must be opened by removing the manhole/handhole or tank cover. See the Tank Cover Removal and Installation section of this manual. Pre -service interior inspections should be restricted to noting defects or damage that may prevent proper operation of the transformer. Inspect for: 1. Moisture on underside of the tank cover or man -hole cover. 2. Loose, shifted, or damaged parts (bushings, fuse holders, etc.). 3. Broken or loose connections. 4. Contaminated insulating liquid (sediment or foreign objects on the tank bottom, dirt or air bubbles suspended in the liquid). Internal damage If concealed internal damage is suspected, it may be necessary to lower the insulting liquid level to complete the inspection. Refer to the Insulating Liquid Maintenance section of this manual. Contaminated insulating liquid If moisture is found inside the tank, or there is evidence that the insulating liquid may be otherwise contaminated, a liquid sample should be taken for analysis. Samples should be drawn from the bottom of the tank. For instruction on sampling the insulating liquid please see the Insulating Liquid Maintenance section of this manual. If moisture is present in the liquid, the transformer must be dried out. Contact your Eaton representative for special instructions on dry -out or other decontamination processes. Three-phase pad -mounted compartmental type installation and maintenance instructions MN202001EN August 2015 External connections ®WARNING Hazardous voltage. Can cause severe injury, death, or damage to equipment. Ground transformer following industry -accepted safe grounding practices before making other electrical connections. De -energize power distribution wires that will be connected to transformer. Verify that wires are de -energized at the transformer before connecting to transformer. Transformers that require no internal inspection or repair may be connected to the system. Transformers must be connected and operated as indicated by the transformer nameplate. Clean bushings and terminals before making connections. Remove dirt, grease or foreign material. Contamination can cause failure of the bushings. Cables connected to the transformer terminals are to have sufficient flex to allow normal pad movement due to ground freeze/thaw and settling. Insufficient cable flex may cause premature failure of the bushings. Ground connections The transformer tank must be connected to a permanent, low -resistance ground. If the tank is not solidly grounded and the transformer is connected to the power distribution system, then the tank should be regarded as energized. An energized tank is extremely dangerous. Contact with an energized tank can shock, burn, or cause death. Three-phase pad -mounted transformers are equipped with two grounding pads for making the ground connection. The pads (see Figure 3) are located on the faceplate of the transformer behind the terminal compartment doors. One pad is in the primary compartment and the other in the secondary compartment. Grounded wye-grounded wye transformer connections Grounded wye-grounded wye winding connection transformers are designed for power distribution systems that have a grounded neutral connector. All windings designed for grounded neutral operation must be permanently and solidly grounded to the system neutral without electrical resistance. Figure 3. Grounding pad. High voltage connections Make connections as shown in the diagrams and information on the transformer nameplate. Transformer neutrals must be connected to system neutrals. Leads and connections that are not used must be insulated from ground and all other leads. Livefront transformer connections Externally clamped porcelain bushings are normally provided for high voltage connection to three-phase pad -mounted livefront transformers. The bushings have tin-plated eyebolt terminals suitable for both copper and aluminum conductors. The bushings are positioned to allow vertical takeoff of primary cables entering from below. Deadfront transformer connections Deadfront three-phase pad -mounted transformers are equipped with universal bushing wells, one-piece bushings, or bushing wells with factory -installed inserts. Universal bushing wells must be field equipped with bushing well inserts before loadbreak cable connections can be made. Bushing well inserts must be compatible with the universal bushing well. Use of improperly rated inserts can cause premature failure of the transformer or its components. Read the manufacturer's instructions furnished with the inserts before installing to determine if they are compatible. Low voltage connections Spade terminals are the standard low voltage connectors used for three-phase pad -mounted transformers. The low voltage bushings are externally clamped to the transformer tank wall. Three-phase pad -mounted compartmental type installation and maintenance instructions MN202001EN August 2015 Accessories Three-phase pad -mounted transformers can be equipped with a variety of optional equipment. Most such accessories are factory installed and no fieldwork is required to prepare them for operation. Liquid level gauge Figure 4. Liquid level gauge. Transformers may be furnished with a liquid level indicator as optional equipment to aid in the systematic inspection of the transformer under load. It consists of a float -arm inside the tank, an indicating pointer and a magnetic coupling between the two across a liquid -tight separation. The gauge may have one or two SPDT (Single Pole Double Throw) alarm contacts to give a remote annunciation of low liquid level. For wiring and contact ratings, refer to the schematic furnished with the transformer. Liquid temperature gauge 6D L IOU ID TEMPS TURE l�l Figure 5. Liquid temperature gauge. Transformers may be furnished with a temperature gauge as optional equipment to indicate the top liquid temperature in the tank in degrees Celsius. The temperature -sensitive element is mounted in a leak -proof well, permitting removal of the thermometer without lowering the oil level. The device is furnished with an additional red pointer to show the highest temperature attained since the last reset. To reset the maximum indicator, turn the knob in the center of the dial. The thermometer may have two SPDT contacts for energizing a fan circuit or for a high temperature alarm. For wiring and contact ratings, refer to the schematic furnished with the transformer. Three-phase pad -mounted compartmental type installation and maintenance instructions MN202001EN August 2015 Pressure -vacuum gauge Figure 6. Pressure -vacuum gauge. Transformers may be furnished with a pressure -vacuum gauge as optional equipment to indicate whether the gas space in the tank is under positive or negative pressure. The pressure will vary depending on the transformer temperature. If the transformer is de -energized or operating under light load in low ambients, the pressure may be negative. CAUTION If the indicator reads zero and does not change under any load condition, the transformer should be checked for a possible leak in the seal. If sufficient air has been absorbed by the liquid during shipment or storage, the transformer may operate indefinitely in the vacuum range, depending upon the loading conditions. This, in itself, is not cause for concern, provided the pressure vacuum gauge does not remain on zero for any length of time - an indication of a leak. The transformer can safely operate in pressures ranging from -2 to +6 psig. The transformer may have pressure vacuum switches with two SPDT contacts for remote alarm on positive and negative pressure. For wiring and contact ratings, refer to the schematic furnished with the transformer. Pressure relief device Figure 7. Pressure relief device. Transformers may have a cover -mounted pressure relief device (PRD) in addition to the faceplate -mounted pressure relief valve (PRV) standard on all three-phase pad - mounted designs. The cover -mounted PRD consists of a self -resetting, spring -loaded diaphragm and a mechanical operation indicator. Should the tank pressure increase above that for which the device is set, the gas pressure will lift the diaphragm and let the gas escape quickly. Immediately after the pressure returns to normal, the diaphragm will reset and reseal the transformer. A mechanical indicator will protrude vertically. This must be reset manually to indicate subsequent operations. The PRD may have SPDT alarm contacts for remote signaling of device activation. For wiring and contact ratings, refer to the schematic furnished with the transformer.

A WARNING Three-phase pad -mounted transformers use conventional transformer oil, R-Temp fluid, or Envirotempl FR31 fluid for an insulating liquid. When the insulating liquid temperature is less than -20 •C (4 OF) for conventional transformer oil, less than 0 •C (32 •F) for R-Temp fluid, or less than -10 •C (14 OF) for Envirotempl FR31 fluid, viscosity is reduced, which may reduce make and break capabilities of loadbreak devices. Below these temperatures, under -oil loadbreak accessories should not be used to make or break a load. Instead, de -energize transformer from a remote upstream source before operating under -oil loadbreak devices. A WARNING Hazardous voltage. Can cause severe injury, death, or damage to equipment. Use a hotstick to service a Bay- O-Net fuse. Do not install a Bay-O-Net fuse to complete an electrical circuit if a fault condition is suspected. Do not re -energize suspected failed equipment. After installing Bay-O-Net fuse, energize transformer from a remote upstream source. Eaton's Cooper Power series Bay-O-Net fuse assemblies are used to protect transformers and distribution systems.

Can cause severe injury, death, or damage to equipment. • Do not operate loadbreak equipment if a fault condition is suspected. Doing so can cause an explosion or fire. • Use a hotstick to operate transformer loadbreak equipment. • After operating transformer loadbreak equipment, check that voltages at transformer terminals are the expected values. Checking voltages verifies that loadbreak equipment operated properly and that electrical circuit conditions are as expected. • Before servicing transformer secondary connected equipment, verify that all transformer secondary terminals have zero voltage and ground the transformer secondary terminals following industry accepted safe grounding practices. Grounding secondary terminals protects against situations such as a standby generator energizing transformer from the secondary circuit. • Before servicing transformer, ALWAYS de -energize the transformer from a remote upstream source and then proceed to ground all primary and secondary transformer terminals following industry accepted safe grounding practices. Grounding secondary terminals protects against situations such as a standby generator energizing transformer from the secondary circuit. • Follow industry accepted safety practices. Utilize protective clothing and equipment when working with loadbreak equipment. A WARNING Three-phase pad -mounted transformers use conventional transformer oil, R-Temp fluid, or EnvirotempT°" FR31 fluid for an insulating liquid. When the insulating liquid temperature is less than -20 °C (-4 •F) for conventional transformer oil, less than 0 •C (32 •F) for R-Temp fluid or less than -10 •C (14 •F) for EnvirotempTm FR31 fluid, viscosity is reduced, which may reduce make and break capabilities of loadbreak devices. Below these temperatures, under -oil loadbreak accessories should not be used to make or break a load. Instead, de -energize transformer from a remote upstream source before operating under -oil loadbreak devices. It is recommended that remote energization be used whenever possible. Operate loadbreak switches using hotstick tool. After loadbreak switch is switched to "OPEN" position, verify that transformer secondary terminals have zero voltage and then ground the secondary terminals to prevent transformer backfeed energization. Two -position loadbreak switch The operating mechanism of the Eaton's Cooper Power series two -position loadbreak switch employs a manually - charged over -toggle stored spring assembly which performs independent of operator speed. The spring -loaded activating mechanism ensures quick loadbreak or loadmake operations in less than one cycle. Incorporated into the switch mechanism are internal stops that restrict the handle orientation to only two positions: "OPEN" and "CLOSED" (see Figure 16). The switch should be hotstick-operated and will require 15 ft-lbs. minimum input torque to operate. Refer to Catalog Section CAB00019ENTwo-Position Sidewall (Horizontal) and Cover (Vertical) Mounted Loadbreak Switches for two -position loadbreak switch ratings. i 11__- RP Figure 16. Two -position loadbreak switch handle and indicator plate. External visible loadbreak switch A CAUTION Always fully cover and lock external visible loadbreak switch window during operation. Failure to cover and lock this window could cause personal injury. Before operating the on/off/ground switch, it is important to ensure the transformer tank has been fully grounded. Always check fluid temperature before operating loadbreak devices. The Eaton's Cooper Power series external visible loadbreak switch is a great way to verify isolation of internal transformer circuitry. Having visual confirmation that the secondary bushings are de -energized saves both time and money, while providing an added safety feature. It is strongly recommended that if breaking load with this switch, the viewing window be fully covered and locked into place. Viewing this switch during operation under load could be dangerous to the human eye. The external visible loadbreak switch is always shipped with a padlockable cover box. It is also important to remember that even after breaking load, the incoming high voltage cables are still live and dangerous. Three-phase pad -mounted compartmental type installation and maintenance instructions MN202001EN August 2015 11 Sectionalizing loadbreak switch Eaton's Cooper Power series sectionalizing loadbreak switch rotates 360' in either direction for alternate source selection. An externally -installed index plate prevents rotation to positions other than the one desired. The switch cannot be switched more than one position without resetting the index plate. A spring -loaded activating mechanism ensures quick loadbreak action and positive contact engagement through all positions. Switching can be accomplished in less than one cycle, and should be performed with a hotstick. To follow are operation examples for the two most common sectionalizing switch configurations. The following is a V-blade switch operation example (see Figure 17): If 'A' is the feeder and it is desired to switch to "B" feeder, then the V-blade switch can be rotated as follows: 1. Set index stop plate between "line A only" and "Open" 2. Rotate switch handle counterclockwise to "Open" Transformer and loop conductor are now "Open" 3. Move index plate between "Open" and "line B only" 4. Rotate switch handle counterclockwise to "line B only" Transformer is now energized for "B" feeder. LINES OPEN 3. Move index plate between "loop thru transformer open"" and "line b only" 4. Rotate switch handle counterclockwise to "line b only" The transformer is now energized for "B" feeder.

Rotate switch handle counterclockwise to "loop thru transformer open"The transformer is now "OPEN" and the loop conductor is electrically connected. Tap -changer Transformers equipped with a tap -changer can be changed from one operating voltage to another. The transformer must be de -energized and grounded before the tap -changer is operated. Operating voltages accessible through use of the tap -changer are indicated on the transformer nameplate. On most three-phase pad -mounted transformers equipped with tap -changers, the tap -changer operating handle is located on the faceplate in the high -voltage terminal compartment. The standard style of tap -changer will have a hotstick- operable handle. There are two styles of tap -changer with this type of handle, each requiring a slightly different method for changing tap settings. 12 Three-phase pad -mounted compartmental type installation and maintenance instructions MN202001EN August 2015 Figure 19. Hotstick-operable tap -changer (Style 1). The tap -changer shown in Figure 19 can be switched to a new tap position as follows: 1. Verify that tank is grounded. De -energize transformer from a remote upstream source. Ground all bushings and terminals before operating the tap switch. 2. Back out lock screw to clear index plate. 3. Rotate handle to desired position. 4. Secure handle in its new position by tightening lock screw through index plate until it bottoms. 5. Padlocking may be accomplished through hole provided. Figure 20. Hotstick-operable tap -changer (Style 11). The tap -changer shown in Figure 20 can be switched to a new tap position as follows: 1. Verify that tank is grounded.

Back out lock screw to clear index plate. 3. Rotate handle to desired position. 4. Secure handle in its new position by tightening lock screw through index plate until it bottoms. Three-phase pad -mounted compartmental type installation and maintenance instructions MN202001EN August 2015 13 Dual -voltage and delta-wye switch A WARNING Hazardous voltage. Can cause severe injury, death, or damage to equipment. De -energize transformer from a remote upstream source before operating non- loadbreak tap -changers, dual -voltage switches, or delta-wye switches. A CAUTION Excessive current. Can cause damage to transformer winding. When dual -voltage or delta-wye switches are set to connect transformer windings in parallel, tap -changers must be in the position shown on the transformer nameplate. Transformers equipped for dual -voltage or delta-wye (reconnectable winding) operations usually have an externally -operable switch mounted on the faceplate in the high -voltage terminal compartment. Units combining dual - voltage and delta-wye may have two separate switches. The transformer must be de -energized and grounded before dual -voltage or delta-wye switches are operated. Attempting to change dual -voltage or delta-wye switches on an energized transformer may result in damage to the equipment and severe personal injury. 4.16 KU Figure 22. Dual-voltage/delta-wye switch (hotstick- operable). 5. Padlocking may be accomplished through hole provided. On some transformers, dual -voltage or delta-wye switches have a lever handle (see Figure 23). Dual -voltage windings are either connected in series (for the higher voltage) or in parallel (for the lower voltage). Dual - voltage and delta-wye switches have two positions. Switch positions are identified on the transformer nameplate and � o`u'U� marked by corresponding numerals on the switch mounting MW plate. When dual -voltage or delta-wye switches are set to connect transformer windings in parallel, tap -changers must be in the position shown on the transformer nameplate. Tap -changers cannot be used to adjust voltage when transformer windings are connected in parallel. Improper tap -changer settings will cause circulating currents in the windings, which will damage the windings and cause failure of the transformer. To change dual winding switch settings: The standard type of dual -voltage or delta-wye switch will have a hotstick-operable handle (see Figure 22). This type of dual -voltage or delta-wye switch can be switched to a new position as follows: 1. Verify that tank is grounded. De -energize transformer from a remote upstream source. Ground all bushings and terminals before operating dual -voltage or delta- wye switch. 2. Back out lock screw to clear index plate. 3. Pull handle out to clear index plate and rotate handle 90°. Drop handle into new position. 4. Secure handle in its new position by tightening lock screw through index plate until it bottoms. Figure 23. Dual-voltage/delta-wye switch (lever handle).

A WARNING Three-phase pad -mounted transformers use conventional transformer oil, R-Temp fluid, or EnvirotempTm FR3Tm fluid for an insulating liquid. When the insulating liquid temperature is less than -20 •C (-4 •F) for conventional transformer oil, less than 0 °C (32 OF) for R-Temp fluid or less than -10 °C (14 •F) for EnvirotempTm FR3Tm fluid, viscosity is reduced, which may reduce make and break capabilities of loadbreak devices. Below these temperatures, under -oil loadbreak accessories should not be used to make or break a load. Instead, de -energize transformer from a remote upstream source before operating under -oil loadbreak devices. IMPORTANT For 75 °C AWR transformers, applications with maximum ambient temperatures exceeding 30 •C or loading in excess of nameplate rating, contact your Eaton representative. Eaton's Cooper Power series VFI transformers utilize vacuum interrupters to provide fault current interruption and load make/break switching capabilities. The VFI transformer uses the same technology used in Eaton's Cooper Power series VFI pad -mounted switchgear. VFI transformers can be specified for either transformer protection or loop protection. A VFI transformer with transformer protection protects the transformer and provides proper coordination with upstream protective devices. AVFI transformer with loop protection protects the loop or downstream section of a feeder. Consequently, when a fault occurs downstream, the VFI breaker trips and isolates the fault, leaving the transformer load uninterrupted. The VFI interrupter mechanism in a VFI transformer has a hotstick-operable handle located on the faceplate of the transformer, with the operating mechanisms configured for ganged three-phase operation (see Figure 24). The VFI interrupter mechanism is opened by pulling the operation handle down to the open position. The VFI interrupter mechanism is closed by briskly pushing the handle up, into the closed position. If the VFI interrupter mechanism has tripped as the result of a fault or overload condition, the mechanism must be reset before it can be closed. To reset the mechanism, firmly pull the operation handle down toward the ground until the latch resets. After the latch has been successfully re -set, the VFI interrupter mechanism can be closed normally. Figure 24. VFI operating handle. OPEN TRIPPED CLOSED Three-phase pad -mounted compartmental type installation and maintenance instructions MN202001EN August 2015 15 Current -sensing transformers (CTs) located inside the VFI transformer provide line current information to the electronic control. When line current exceeds the minimum trip setting, the control initiates a signal which causes the VFI interrupter mechanism to trip and then interrupt the circuit. All three phases will open when the VFI interrupter mechanism is tripped, regardless of whether the trip was single-phase or three-phase initiated. Refer to Service Information S285-75-1, Tri-Phase, TPG, and TPG with SCADA Electronic Control Installation and Operation Instructions for electronic control operation instructions.

Can cause severe injury, death, or damage to equipment. Depending on configuration, Arc -Strangler fuses or switchblades may be energized even when in the `open" position. Refer to catalog section 240-60 for further information. Arc -Strangler loadbreaking device with NX® fusing NX® full -range current -limiting fuses up to 15.5 kV can be ordered with an integral Arc -Strangler® loadbreaking device. These in -air devices are mounted on the faceplate of the transformer, The Arc -Strangler device has the same operating characteristics as the basic NX clip -style fuse, along with loadbreaking capabilities. The Arc -Strangler loadbreaking device is a spring -loaded sliding sleeve that extinguishes the arc drawn between the mounting contacts and the fuse conductor when the fuse is opened while load current is flowing. All magnitudes of current through the continuous current rating of the fuse can be interrupted positively and safely under proper conditions. A pull -ring at the top of the fuse assembly (for hotstick operation) and a hinge at the bottom complete the loadbreak device. Arc -Strangler switchblades Switchblades with integral Arc -Strangler loadbreaking devices are available for use in NX type fuse mountings. Arc -Strangler switchblades are designed to break load current only (up to 200 A) and do not incorporate a fuse of any type for overload or fault interruption. Surge arresters Surge arresters are used in three-phase pad -mounted A WARNING Hazardous voltage. Can cause severe injury, death, or damage to equipment. De -energize transformer from a remote upstream source before servicing or operating surge arresters or disconnect switches. Check that all transformer terminals and bushings have zero voltage. Ground transformer following industry accepted safe grounding practices. A CAUTION Excessive test voltage can damage surge arresters. Disconnect surge arresters before running impulse or applied potential tests on the transformer. transformers to protect underground distribution equipment and cable from overvoltage surges. During steady state conditions, line -to -ground voltage is applied continuously across the arrester terminals. When surges occur, the arrester immediately limits the overvoltage to the required protective level by conducting the surge current to ground. Upon passage of the surge, the arrester returns to its initial state, conducting minimal leakage current. Surge arresters should be installed only on systems where the power frequency voltage at the arrester does not exceed published maximum continuous operating voltage (MCOV) values. The transformer should not be tested (impulse or applied potential) with the arrester connected. If connected during impulse tests, the arrester will clamp the discharge voltage applied by the test equipment. If the arrester is connected to the transformer during an applied potential test, there is a possibility that the arrester will be damaged. Disconnect surge arresters before tests are performed on the transformer. Arresters should be reconnected immediately after tests are completed. Under -oil MOV arrester Eaton's Cooper Power series heavy-duty distribution -class under -oil MOV arrester is designed to be mounted inside the transformer tank (see Figure 25). Internal, under -oil mounting of the arrester prevents shortened arrester life due to surface contamination, wildlife damage, vandalism, or moisture ingress. Under -oil arresters are designed to operate when submerged in oil. It is recommended that the average oil temperature not exceed 90 °C and that the maximum oil temperature not exceed 125'C.

Arrester and tank ground connections must be completed before the transformer is connected to the high -voltage or low -voltage lines. Proper connection places the arrester in a direct shunt relationship to the transformer insulation. Maintenance Exterior maintenance On an annual or more frequent interval, inspect all exposed surfaces for evidence of tampering, battered metal, gouges, etc. Dents or deformities should be repaired at once. Scratched or weathered paint or protective coatings should be touched up promptly. Keep the area around the transformer clean. Do not store tools, materials or equipment on or against the transformer. Cabinet interior maintenance A WARNING Hazardous voltage. Can cause severe injury, death, or damage to equipment. De -energize transformer from a remote upstream source before opening cabinet and doing cabinet interior inspection or maintenance. Check that all transformer terminals and bushings have zero voltage. Ground transformer following industry accepted safe grounding practices. Periodically inspect the terminal compartment interior and all operating equipment. Check all gauges and controls for proper operation. Repair or replace damaged or defective equipment. Inspect drain cocks, plugs, fuse mountings, and switches. Look for evidence of insulating liquid seepage around tank - wall gaskets, seals, etc. Repair as required. Replacement of gaskets or seals in the tank wall may require that the tank be opened and the insulating liquid lowered to the appropriate level. For instruction on opening the tank and for draining and replacing the insulating liquid, refer to the Insulating Liquid Maintenance section in this manual. Tank internal maintenance (For Envirotran@ Transformers see the Envirotran Transformers section of this manual before continuing) A CAUTION Elevated Pressure. Can cause personal injury or damage to transformer. Release internal pressure with pressure relief device before removing tank cover, manhole cover or handhole cover. A WARNING Hazardous voltage. Can cause severe injury, death, or damage to equipment. De -energize transformer from a remote upstream source before opening cabinet and doing internal tank inspection or maintenance. Check that all transformer terminals and bushings have zero voltage. Ground transformer following industry accepted safe grounding practices. Service to bushings or equipment inside the transformer tank will require that the tank be opened and the insulating liquid lowered to the appropriate level. Before opening the transformer tank, read the Insulating Liquid Maintenance section in this manual. The Liquid Maintenance section explains safety precautions that should be taken and gives instructions on how to prevent insulating liquid contamination. Precautions must be taken to prevent dirt or moisture from entering the opened transformer tank. Contamination of the insulating liquid will prevent the transformer from operating properly and may cause serious damage to the transformer. Three-phase pad -mounted transformers may have either bolt -on or weld -on main tank covers. Bolt -on covers can be removed to access the tank interior. Access to the interior of a transformer with a weld -on tank cover is typically through a manhole/handhole. To gain additional internal access to tanks with weld -on tank covers, the tank cover must be cut open. Tank cover removal and installation (For Envirotran Transformers see the Envirotran Transformers section of this manual before continuing) A CAUTION Elevated Pressure.

Can cause severe injury, death, or damage to equipment. Before cutting open a Weld- on tank cover, fill tank headspace with nitrogen gas. Keep nitrogen gas flowing while cutting. Keep tank headspace filled with nitrogen until cutting is finished. Transformer tanks are factory -sealed to prevent ingress of ambient air and moisture. Do not open under any precipitation conditions. Explosive gases can develop inside a transformer tank headspace during the life of the transformer. It is strongly recommended that weld -on cover removal be done only in a controlled repair facility by experienced maintenance personnel. To prevent explosions, the following procedures must be followed during weld -on cover removal: 1. Verify that tank is grounded. De -energize transformer from a remote upstream source. Ground all bushings and terminals before removing cover. 2. Relieve internal tank pressure by operating pressure relief valve. 3. Remove manhole/handhole cover as outlined in the Tank Cover Removal and Installation section of this manual. 4. Drain insulating liquid to the top of core clamp as outlined in the Insulating Liquid Maintenance section of this manual. 5. Allow transformer to sit with manhole/handhole removed for a minimum of 24 hours to allow explosive gases to escape. 6. Place a rubberized blanket on top of core clamp and completely cover core/coil assembly to protect core/coil assembly from weld spatter contamination during cover cutting. 7. Remove pressure relief valve and attach a nitrogen source in its place. 8. Fill headspace with nitrogen with manhole/ handhole cover still removed. Nitrogen gas will help prevent a volatile gas explosion while tank cover is being cut off. 9. While continuing to keep nitrogen flowing into the headspace, use carbon air arc machinery or a hard - wheel grinder to cut cover weld. 10. Thoroughly clean tank cover to help prevent contamination of insulating liquid when removing cover. Remove all dirt, grease, and moisture. 11. Remove tank cover from tank. Weld -on tank cover installation 1. Grind smooth and then clean cover, removing all weld spatter accumulated during cover removal. 2.

Tighten cabinet hardware to 20 ft-lbs. torque. Insulating liquid maintenance Transformer tanks are factory -sealed to prevent ingress of ambient air and moisture. Do not open under any precipitation conditions. If it is necessary to drain and refill the transformer, special care should be taken to avoid the entrapment of gas bubbles in the system. Gas bubbles have lower dielectric integrity than the insulating liquid and will degrade the performance characteristics of the insulating system. Conventional oil -filled transformers Refer to IEEE Std C57.106TM-2006 standard, "Guide For Acceptance and Maintenance of Insulating Oil in Equipment for additional guidelines when testing and handling conventional transformer oil. Periodic maintenance tests should be performed. R-TranTM transformers Eaton's Cooper Power series R-TranTM transformers are filled with R-Temp fluid. R-Temp fluid is a non -toxic, readily biodegradable, less -flammable (high fire point), high molecular weight hydrocarbon dielectric fluid. Refer to IEEE Std C57.121TM-1998 standard, "Guide for Acceptance and Maintenance of Less Flammable Hydrocarbon Fluids in Transformers." Periodic maintenance tests should be performed on the same schedule as would be used for transformers of similar application filled with conventional transformer oil. Contact your Eaton representative for additional handling guidelines for R-Temp fluid. Mixtures of R-Temp fluid and conventional transformer oil R-Temp fluid is fully miscible with conventional transformer oil. There is no known detrimental performance impact when R-Temp fluid is mixed with conventional transformer oil. Conversely, except for some reduction in flash and fire points, the same is true for conventional transformer oil mixed with R-Temp fluid. Conventional transformer oil content of >3% in R-Temp fluid lowers the fire point below 300 °C. Measure the ASTM flash and fire points if the presence of conventional transformer oil is suspected. If flash or fire points fall below the minimum values required, retrofilling may be required. Envirotran® transformers Eaton's Cooper Power series Envirotran® transformers are filled with EnvirotempTM FR3TM fluid. EnvirotempTM FR3TM fluid is a less -flammable (high fire point) dielectric fluid based on edible seed oils. Periodic maintenance should be performed on the same schedule as would be used for transformers of similar application filled with conventional transformer oil. Basic recommended tests for EnvirotempTM FR3TM fluid are dielectric strength, moisture content, and flash and fire points. Envirotran transformer tanks are shipped from the factory with a dry nitrogen -filled headspace. Internal pressure should not be equalized with atmosphere by manually opening the pressure relief valve device unless access to Bay-O-Net fuses or other internal tank components is required. If internal service is required If the tank cover or manhole/handhole must be removed for internal service, exposure time to ambient air should be minimized. Avoid exposure times greater than 24 hours. Immediately after service is completed, replace the cover or man hole/hand hole. The tank headspace must then be purged and recharged with dry nitrogen. Envirotran transformers are equipped with one or two 1/4" fill valves on the upper left and/or upper right corners of the face plate and are intended for the recharging process. The following steps should be followed when purging and recharging Envirotran transformers: 1. Verify that tank is grounded. De -energize transformer from a remote upstream source. Ground all bushings and terminals. 2. Release internal pressure by operating pressure relief device. 3. Fill headspace with dry nitrogen through one of the 1/4" fill valves to a pressure of 2-3 psig. 4. Release internal pressure by operating pressure relief device. 5. Refill headspace with dry nitrogen through one of the 1/4" fill valves to a pressure of 2-3 psig. Internal pressure must be maintained for at least four hours prior to transformer energization to verify seal integrity. Three-phase pad -mounted compartmental type installation and maintenance instructions MN202001EN August 2015 23 Bay-O-Net fuse replacement When replacing fuses in FlapperTM style Bay-O-Net fuse assembles, refer to Bay-O-Net Fuse Re -Fusing Instructions in this manual. Follow the same procedure as with conventional oil -filled transformers. Operation Eaton designs its transformers to operate at rated load with a temperature rise equal to or less than the temperature rise printed on the transformer's nameplate. Operating transformers in excess of IEEE Std C57.91TM-2011 standard will result in accelerated loss of insulation system life. The coil insulation has been carefully made with thermally - upgraded materials to ensure long life at rated loads. Severe and prolonged overloads of mineral oil -filled transformers will result in overheating and accelerated aging of the insulation, which may lead to premature failure. PEAKTM transformers have extended life and can be operated at higher temperatures. Refer to IEEE Std C57.154TM-2012 standard for details. Mixtures of EnvirotempTM FR31 fluid and conventional transformer oil EnvirotempTM FR3TM fluid is fully miscible with conventional transformer oil. There is no known detrimental performance impact when EnvirotempTM FR3TM fluid is mixed with conventional transformer oil. Conversely, except for some reduction in flash and fire points, the same is true for conventional transformer oil mixed with EnvirotempTM FR3TM fluid. Conventional transformer oil content of >7% in EnvirotempTM FR3TM fluid lowers the fire point below 300 °C. Measure the ASTM flash and fire points if the presence of conventional transformer oil is suspected. If flash or fire points fall below the minimum values required, retrofilling may be required. To maintain its exceptional environmental classification, mixing of EnvirotempTM FR3TM dielectric coolant with any other fluids should be avoided. Contact your Eaton representative for additional handling guidelines for EnvirotempTM FR3TM fluid. Sampling insulating liquid Before sampling the insulating liquid, verify that the tank is grounded. De -energize the transformer from a remote upstream source. Ground the bushings and terminals. Refer to ASTM D923 "Standard Practices for Sampling Electrical Insulating Liquids" for sampling techniques. A sample of the liquid should be taken when the liquid tem- perature is equal to or greater than the surrounding air to avoid condensation of moisture on the liquid. Containers used for sampling liquid should be clean and dry large mouth glass bottles. Make sure that the liquid being sampled is representative of the liquid in the unit. Sufficient liquid must first be drawn off to ensure that the sample will be from the bottom of the tank, and not the liquid stored in the sampling pipe Testing insulating liquid For the dielectric strength of the insulating liquids, follow the technique as specified by ASTM D877, "Standard Test Method for Dielectric Breakdown Voltage of Insulating Liquids Using Disk Electrodes." If the dielectric strength of the liquid drops below 26 W,, it should be filtered until it tests at 26 kV or better. Filtering insulating liquid Conventional transformer oil, R-Temp, or EnvirotempTM FR3TM fluids can be filtered by means of a filter press. The filter press is effective for removing all types of foreign matter, including finely divided carbon and small amounts of moisture. The purifier equipment consists of a specifically proportioned filter press, a positive volume gear pump, driving motor, combined drip pan and mixing tank, necessary piping, valves, strainer, gauges and drying oven. Follow manufacturer's instructions for purifier equipment operation. Filtration should be continued until the dielectric test of the insulating liquid is 26 kV or better. When filtering R-Temp or EnvirotempTM FR3TM fluid, the filtering equipment must be free of contaminants and other liquids. The presence of other liquids may alter the physical and electrical characteristics of R-Temp or EnvirotempTM FR3TM fluid. This could result in a reduction of fire point. Lowering insulating liquid level 1. Verify that tank is grounded. De -energize transformer from a remote upstream source. Ground all bushings and terminals. 2. If cover removal is required, remove cover as outlined in Tank Cover Removal and Installation section of this manual. 3. Prepare a clean, dry storage container to receive liquid. 4. Use pumps and hoses that have not been contaminated by contact with dissimilar liquids. Use a metal or non -rubber hose. Oil dissolves the sulfur found in rubber and will prove harmful to conductor material. 5. Attach pump intake line to drain valve on transformer tank. 6. Place output line nozzle on bottom of storage container. Do not permit liquid to splash into receiving container. Splashing will introduce air and moisture into liquid. 7. Do not lower liquid below top of core clamp unless absolutely necessary. Exposing coils may allow moisture to contaminate coil insulation. 24 Three-phase pad -mounted compartmental type installation and maintenance instructions MN202001EN August 2015 Restoring insulating liquid level CAUTION It may be necessary to add extra liquid to the storage container from a reserve supply to replace the small quantity lost in the pump and lines and to prevent aeration of replacement liquid. If it is necessary to drain and refill the transformer, special care should be taken to avoid the entrapment of gas bubbles in the system. Sufficient time should be allowed between refilling and energization of the transformer to be sure that any gas bubbles created during the process have been dissipated. 1. Pump from bottom of temporary storage tank. Do not permit intake line to draw in air, since air bubbles will lower dielectric integrity of insulating system. 2. To prevent aeration at hose output, locate hose output below liquid surface 3. Pump slowly. If tank cover is not attached to tank, fill transformer to fill line marked on inside of transformer faceplate. If the tank cover is attached to tank, liquid level gauge may be read directly. On transformers that are not gauge -equipped, liquid level should be filled to bottom edge of liquid level plug hole (see Figure 3). Applicable standards 1.
