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
1. Good frequency equivalence. The measured current waveform is sine wave, the difference between frequency and power frequency is 5Hz, use 45Hz and 55Hz two frequency to test.
2. Strong anti-jamming ability, use different frequency method , assorted with modern hardware and software filtering techniques, make the device with strong anti-jamming ability, test results stable and reliable. Error caused by 15V/50Hz interference voltage: 0.001Ω
3. High precision, can test the ground network of small impedance.
4. Powerful: can test all characteristic parameters of grounding devices, only only ground impedance but also resistive component, reactance component can be measured
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
