Unload Current: IO<10%                               Voltage Ratio of Measurement Windings: 1000:1

 
 

Over Current Ability: Continuous working for 300S under 120% rated current, then thermal damage or distortion of the winding shall not be occurred.
Over Voltage Ability: Overvoltage at 110% UH (880kV) for 60s, then it shall not happened any insulation damage for the testing transformer.
Insulation Level: 10kV/1min (low voltage input terminal to earth)
Partial discharge level: ≤3pC, under 100% rate voltage;     ≤2pC, under 80% rate voltage
Noise: ≤60dB                          Dielectric loss: <0.4%
Operating Time: Working for 60 minutes allowed at 100% rated current & voltage; Continuous working allowed at 80% rated current & voltage; and temperature rise of transformer windings is less than 40K.
Protection: Equip with 3kV surge arrestors.
