HVI produces several lines of power frequency output AC high voltage test sets.
These testers perform AC withstand testing to verify the AC voltage integrity of insulation.
They can test many types of electrical apparatus, including:
Vacuum bottles
SG
Circuit breakers
Reclosures
Iso phase bus
Motor and generator coils
Hot sticks
Aerial lifts
Bushings
Rubber gloves
Many other MV and HV loads
Some models are corona free, designed to serve as AC sources for partial discharge and power factor/tan delta testing. These products include many control configurations and range from portable sets up to 20 kVA and factory use models up to 40 kVA. Voltage ratings are from 5 kV AC – 300 kV AC.
