The HVT Series AC hipot testers are an economical solution to AC field-testing of bucket trucks, aerial platforms, vacuum interrupters, breakers, switchgear, and other electrical apparatus. Models 100HVT and 120HVT offer 100kV or 120kV respectively. Both models are handcart mounted for portability and come complete with input line cord, interconnecting cable and ground leads.
The 100HVT and 120HVT series test sets are specifically designed in meeting test procedures of the ANSI/SIA A92.2 1990 specification applied to the insulating boom of work platforms and bucket trucks. The HVT series assures accurate voltage measurements using an external 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.
