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:
Iso phase bus
Motor and generator coils
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.
