Open Circuit Test (core loss test): TEST CONDITION: Apply variable voltage to primary coil (115V terminals) from 115-180VAC at 60Hz. No load on secondary coils. 1. Primary V = 115VAC, Primary I = .03A or core loss is 3.4Watt. 2. Primary V = 140VAC, Primary I = .03A 3. Primary V = 160VAC, Primary I = .05A 4. Primary V = 180VAC, Primary I = .10A Short Circuit Test (copper loss test): TEST CONDITION: Apply variable voltage to primary coil (115V terminals) from 1-20VAC at 60Hz and short circuit on secondary coils and test the primary voltage and current. The result is 8.1V and 6.1A or 49.3Watt which is the maximum rated copper loss TEST CONDITION: Apply dielectric meter between primary coils and secondary coils; and increase voltage up to 3500VAC. No initiate any spark. TEST CONDITION: Input 115VAC 60Hz to the primary coil; parallel 2 secondary coils, 5 ohm 250W resistors as dummy load and room temperature at 25 degree C. Temperature rises 5 degree C after an hour test at load test #5. 1. Primary I = 0.03A, Secondary V = 38.9VAC at 0.0A, Power = 0 Watt 2. Primary I = 1.38A, Secondary V = 38.3VAC at 3.83A, Power = 146 Watt 3. Primary I = 2.72A, Secondary V = 37.7VAC at 7.54A, Power = 284 Watt 4. Primary I = 5.24A, Secondary V = 36.7VAC at 14.68A, Power = 539 Watt 5. Primary I = 7.50A, Secondary V = 35.5VAC at 21.30A, Power = 756 Watt Dimension – 5.1†Diameter x 3.1†High.
