3157-01 AC Grounding HiTester ● Measure insulation of high-voltageGrounding Tester The 3157 01 AC Grounding HiTester is designed to measure whether the metal enclosure of an electrical equipment is connected to the ground terminal at sufficiently low resistance levels. It also can be used to evaluate the grounding conditions of large scale electrical installations. Measurement is carried out by using a high current according to the specifications of the measurement object, and determining the voltage drop at the
