Variable Inductance Resonant Test System normally basic test equpment for GIS, CABLE, Bushing, CT/PT/CVT, transfromer, HV switch ...
Voltage Rating: 50kV ~ 2000kV
-AC inductance resonant reactor (50Hz/60Hz)
-High voltage divider
-Current Limit inductance
-Automatic control system
- Peak voltmeter
When reactor high current and high power, or long cycle time, equipping cooling fins will be necessary.
The above systems the filter are done by single π, for better filter performance, double π or tripple π will be adopt.
The reactor or divider/capacitor's top eletrode can be single stage corona ring or two stages corona rings. If not limit by the roof height, we proposal double rings.
For high voltage divider, double rings or single rings.
