Our testing standards meet or exceed the standards of the American National Standards Institute (ANSI) as well as those of new manufacturers. The remanufacturing process starts with the removal of the core and coil assembly from the tank. The core steel is dismantled and the old coil is discarded. The core steel is cleaned and inspected for damage caused by electrical stresses or general poor quality. If determined to be of good quality, the design process begins. The design process is initiated by careful measurement of the existing core steel. Based on these measurements and loss criteria of the customer, a computer generated coil design is created. This design is specific to the individual transformer based on voltage and KVA rating, keeping in mind the original manufacturers specifications. A new coil is then wound to the specific design criteria. The winding process utilizes the highest quality materials. We use new Essex copper magnet wire with a heavy Formvar (105EC) coating. We selected the heavy Formvar coating over the lighter filmed wire because of the superior turn -to -turn short circuit capability. Essex heavy Formvar wire is manufactured in Fort Wayne, Indiana exclusively for the transformer industry. The insulation used is an epoxy coated kraft paper developed by Westinghouse for the transformer industry. During the bake out process, the epoxy bonds the wire to the paper further increasing the short circuit strength of each coil. Following the winding process, the core steel is assembled around the new coil. The core and coil assembly is then placed in our oven and baked at 250EF for a minimum of 12 hours to insure proper bonding. The core and coil assembly is then removed from the oven hot and placed directly into the transformer tank. The tank is then filled with oil to eliminate absorption of moisture from the atmosphere as it cools. Only new PCB -Free (0 ppm) oil is used in transformers rebuilt by Solomon Corporation. All oil must pass a 32 KV dielectric test prior to use. Transformers in voltage classes above 15 KV will be filled under vacuum. Solomon Corporation only remanufactures transformers less than 45 ppm PCB. This is validated by testing the PCB content of the original oil in the unit, which was removed prior to refilling with new oil. Solomon Corporation uses an independent lab that uses the gas chromatograph electron capture method of PCB analysis. 2 During the rebuilding process any components (bushings, switches, etc.) found to be defective will be, whenever possible, replaced with original manufacturers' components. If replacement components are not available from the original manufacturer, we will utilize components manufactured by the RTE Corporation of Pewaukee, Wisconsin and Warco, Inc. of Marthasville, Missouri. To insure proper sealing of the transformers, new Nitril Buna N-70 gaskets are used in the reassembly process. New pressure relief valves, manufactured by Qualitrol Corporation of Fairport, New York, are added to the transformers. Prior to electrical testing, the unit will be leak tested.

Our testing standards meet or exceed the standards of the American National Standards Institute (ANSI) as well as those of new manufacturers. The reconditioning process begins by determining the condition of the transformer to be repaired. Two preliminary tests are run on the unit, Turn Ratio Test and Megohm Test. The first test checks the ratio of primary to secondary turns and polarity. The Megohm Test measures the amount of moisture in the coil. If the results of these tests are deemed satisfactory, the repair process begins. Solomon Corporation only reconditions transformers less than 45 ppm PCB, by testing the PCB content of the original oil in the unit, before removal and disposal. The repair process starts by vacuum transferring the old oil to bulk storage facilities for ultimate disposal at the cement kilns in S.E. Kansas Solomon Corporation uses an independent lab that uses the gas chromatograph electron capture method of PCB analysis. A visual inspection is then done to insure that the core and coil assembly is intact, all switches are in good working order and all clearances to ground are up to specifications. All bushings and external switches are then removed and closely inspected for damage (cracks, chips, carbon, etc.). Any components found to be defective will be, whenever possible, replaced with original manufacturers' components. If replacement parts are not available from the original manufacturer, we utilize components manufactured by the RTE Corporation of Pewaukee, Wisconsin and Warco, Inc. of Marthasville, Missouri. To insure proper sealing of the transformers, only new Nitril Buna N-70 gaskets and o-rings are used in the reassembly process. New pressure relief valves are also added to the transformer to insure proper venting. Prior to refilling the transformer, the core and coil assembly is flushed with new oil. This fluid is removed and the unit is filled to the proper level with new PCB -Free oil. Transformers in voltage classes above 15 KV will be filled under vacuum. The unit is leak tested following lid placement and then proceeds to the test facility. Solomon Corporation, Procurement Dept. March, 2003 TEST PROCEDURES ON DISTRIBUTION AND SUBSTATION TRANSFORMERS Tlansformer Turn Ratio TUt: To check ratio of primary to secondary turns of the related voltage connection. Mega m Test: To measure the resistance of the insulation. carbonized paths to ground. Induced Potential Test: It also checks polarity and phase relation This will detect the presence of moisture or Twice rated voltage at 400 Hertz is fed into unit which checks all electrical connections and voids in insulation_ Applied Po ntial Test (,A C. Hinot): High voltage per ANSI Standards is fed into both high and low voltage windings. This test checks clearance to ground and bushing insulators. Exciting Current an No Load Toss Test: To measure the no load loss of the core steel and the percent of exciting current in the transformer. rmped ince and Load Lnss Test: To measure full load losses and the percent of impedance. Doble Insulation and Power Fact=11,91t= Power factor tests are run on all substation type transformers. This test determines the condition of the insulation_ It also determines the condition of the transformer bushings. OIL TEST PROCEDURES Solomon Corporation uses only new PCB -Free (0 ppm) oil. All oil purchased is accompanied by an authorized certificate of analysis from the mamufacturer. In addition, we test the acidity content and the dielectric strength (32 KV minimum) to insure that it meets our specifications for moisture content.
