VLF technology applies high AC voltages to cables, motors, generators, and other highly capacitive loads using test equipment that is portable, easier to use, and more economical than conventional methods.

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.

HVI’s combination high voltage DC proof testers and HV megohmmeters are available in field portable and benchtop models for testing dielectric strength and insulation resistance with a single instrument.

Oil Dielectric AC test sets provide replicable, accurate measurement of breakdown voltage of insulating oils used in electrical equipment. These lightweight, rugged units are designed for field and laboratory use.

The ALT Series of AC Hipots were designed for both factory and field testing of aerial lifts and liners but with output power ratings of up to 7kVA they are equally suited for testing other field and substation apparatus.

HVI has extensive knowledge and field experience in fault locating and cable testing along with the best tools for the job. Fault locating requires more than just a thumper. Efficient fault locating requires the convergence of knowledge, methodology, and the right hardware.

The DVR Series offers a 150 kV and a 300 kV AC/DC model designed with precision resistor/capacitor networks that provide low voltage outputs proportional to the applied high voltage input.

The Ω-Check® concentric neutral resistance tester (Model OCK-30) is unique and useful. It injects an AC current through a live cable neutral and measures the voltage drop to calculate the resistance of that neutral.

The PPD Series DC and the TPFT Series AC power supplies are designed for OEMs requiring high voltage supplies to include in their product design, for deployment in factory testing manufactured products, or to provide a testing service or some other application.
