Hioki 3157 AC Grounding HiTester

Overview

The Hioki 3157 AC Grounding HiTester is designed to verify that the metal enclosure of electrical equipment is connected to the ground terminal at a sufficiently low resistance. Using the AC four-terminal method, it passes a high test current (up to 31 A) through the connection and measures the resulting voltage drop to determine grounding continuity. It is ideal for production-line safety testing and for evaluating the grounding conditions of large-scale electrical installations.
