Open Circuit Test (core loss test): TEST CONDITION: Apply variable voltage to primary coil (115V terminals) from 115-140VAC at 60Hz. No load on secondary coils. 1. Primary V = 115VAC, Primary I = .04A or core loss is 3Watt. 2. Primary V = 140VAC, Primary I = .09A core lost is 9 watt 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 6.3V and 3.48A or 21Watt 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, resistors as dummy load and room temperature at 25 degree C. 1. Primary I = 0.04A, Secondary V = 406VAC at 0.0A, Power = 0 Watt 2. Primary I = 4.5A, Secondary V = 375VAC at 1.3A, Power = 470 Watt Dimension – 4.9” Diameter x 3.1” High. Wire lead – 12” color-coded.
