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 = .01A 2. Primary V = 140VAC, Primary I = .01A 3. Primary V = 160VAC, Primary I = .02A 4. Primary V = 180VAC, Primary I = .04A 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. The test result is 9.25V and 0.83A on primary coils which is the maximum rated current test 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 #3. 1. Primary I = 0.01A, Secondary V = 25.2VAC at 0.0A, Power = 0 Watt 2. Primary I = 0.56A, Secondary V = 24.0VAC at 2.4A, Power = 58 Watt 3. Primary I = 1.06A, Secondary V = 23.1VAC at 4.6A, Power = 107 Watt Dimension – 3.8†Diameter x 2.3†High.
