Brewster, NY. Haefely Hipotronics, a developer and provider of high-voltage test systems and measuring devices, has announced the launch of the 100-kV HVT-DI Series AC hipot testers, which the company describes as the modern digital solution to AC field-testing of bucket trucks, aerial platforms, vacuum interrupters, breakers, switchgear, and other electrical apparatus.
The 100-kV HVT-DI is suitable for factory and acceptance test on
- aerial platforms;
- bucket trucks;
- switchgear, vacuum bottles, and vacuum interrupters;
- hot sticks, gloves, and ropes; and
- hydraulic hoses.
The 120-kV model is specifically designed for ANSI/SIA A92.2 specification procedures for testing insulating booms on work platforms and bucket trucks. In addition, the 100-kV model is designed for high output current—up to 100 mA at the 50-kV tap. The instruments assure accurate voltage and current measurements using a high-voltage divider and double current meter in the return leg of the high-voltage transformer. A guard circuit prevents stray or surface leakage from being measured by the current meter. The unit is equipped with a fast-acting fuse, an external interlock, and E-stop.
Available 30-kV and 60-kV models are designed to perform quick and accurate AC dielectric tests.
Haefely Hipotronics is a part of Hubbell Inc. with central offices in Basel, Switzerland, and Brewster, NY.
