The HVT Series AC Hipot Tester are an economical solution to AC field-testing of vacuum interrupters, breakers, switchgear, and other electrical apparatus. Models 30HVT, 60HVT, 100HVT and 120HVT offer 30kV, 60kV, 100kV or 120kV respectively.
All models are handcart mounted for portability and come complete with input line cord, interconnecting cable and ground leads. The HVT series test sets are specifically designed to perform quick and accurate AC dielectric tests. The HVT dielectric testing equipment accurate voltage measurements using an internal high voltage divider, rather than less accurate primary metering.
The HVT series also features a triple range current meter in the return leg of the high voltage transformer for accurate current measurements. A guard circuit prevents stray or surface leakage from being measured by the current meter. To ensure safe operation the unit is equipped with a fast acting circuit breaker, zero start interlock, and provision for an external interlock.
