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 = .02A
3. Primary V = 160VAC, Primary I = .03A
4. Primary V = 180VAC, Primary I = .07A
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 11.5V and 1.74A 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 #5.
1. Primary I = 0.01A, Secondary V = 15.3AC at 0.0A, Power = 0 Watt
2. Primary I = 0.42A, Secondary V = 15.1VAC at 3.0A, Power = 45 Watt
3. Primary I = 0.82A, Secondary V = 14.7VAC at 5.88A, Power = 86 Watt
4. Primary I = 1.56A, Secondary V = 14.1VAC at 11.25A, Power = 158 Watt
5. Primary I = 1.90A, Secondary V = 13.8VAC at 13.78A, Power = 190 Watt
