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 = .02A or core loss is 2.3Watt. 2. Primary V = 140VAC, Primary I = .03A 3. Primary V = 160VAC, Primary I = .05A 4. Primary V = 180VAC, Primary I = .15A 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 12V and 3.48A or 42Watt 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, 50 ohm 50W resistors as dummy load and room temperature at 25 degree C. Temperature rises 10 degree C after an hour test at load test #3. 1. Primary I = 0.02A, Secondary V = 360VAC at 0.0A, Power = 0 Watt 2. Primary I = 0.20A, Secondary V = 358VAC at 0.05A, Power = 17 Watt 3. Primary I = 2.45A, Secondary V = 345VAC at 0.68A, Power = 235 Watt Dimension – 4.8†Diameter x 3.2†High.
