ZG47 HT Instruments HiPot

The ZG47 is a HiPot from HT Instruments. HiPot, or high potential, is a class of electronic test equipment used to verify electrical insulation. Engineers use HiPot-testing instruments on cables, wires, circuit boards, appliances, electric motors, and transformers. As a product ages, its insulation may break down and result in current flow leakage. HiPot testers keep engineers safe from current leakages by detecting gaps and defects in the electronic device. Dielectric Testers, Insulation Testers, and Megohmmeters are similar to HiPot testers. Popular manufacturers include Biddle, Megger, Fluke, Associated Research, Quadtech, Instek, and Slaughter.
