The ground grid grounding resistance tester is suitable for testing the grounding resistance of large-scale electric power grids such as power departments and substations. The 5A grounding grid grounding resistance tester is suitable for testing the power frequency grounding impedance, touch voltage, cross Step voltage, equal power frequency characteristic parameters and soil resistivity.
The ground grid grounding resistance tester is suitable for testing grounding resistance in various places such as substation ground grids (4Ω), power plants, microwave stations (10Ω), lightning rods (10Ω) and other places. The grounding resistance test output of the large-scale ground grid adopts the dual frequency test of 45hz and 55hz. The maximum output current of the test current is 5A, which will not cause the potential of the grounding device to be too high during the test. The grounding resistance tester of the 5A ground grid also has Strong anti-interference ability, which can be measured without power outage.
