Earth Insulation Tester

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

Features

1. Good frequency equivalence. sine wave(measured current wave), two frequencies for testing.

2. Strong anti-jamming ability, test results stable, reliable. Error caused from 15V/50Hz disturbance: 0.001Ω

3. High precision, can test the ground network of small impedance.

4. Powerful: test all characteristic parameters like ground impedance, resistive and reactance component

5. disconnection alarm function

6. Easy to operate, menu operated, directly display the test results.

7. Do not need high current wire.

8. small volume, little weight, convenient to carry
