3A Grounding / Earth Resistance Tester For Large Earthing Grid
This device applies to test frequency ground resistance, contact voltage, pace voltage and earth electric resistivity.
Can test substation grounding grid (4Ω), fire and water electric power plants, microwave stations (10Ω), lightning rod multi-purpose model (10Ω). It adopts different frequency anti-jamming technique, can get the data under 50Hz in strong interference circumstance. measured current from 0~3A, which will not cause the electric potential of the grounding device too high.
It’s with strong anti-interference ability, so no need power off during the test
