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 = .04A
4. Primary V = 180VAC, Primary I = .06A
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 9.1V and 5.2A or 47.3Watt 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 = 34.9VAC at 0.0A, Power = 0 Watt
2. Primary I = 1.11A, Secondary V = 34.4VAC at 3.45A, Power = 119 Watt
3. Primary I = 2.17A, Secondary V = 33.9VAC at 6.78A, Power = 230 Watt
4. Primary I = 4.19A, Secondary V = 32.9VAC at 13.14A, Power = 432 Watt
5. Primary I = 6.04A, Secondary V = 32.1VAC at 19.26A, Power = 618 Watt
