Audited Supplier KDW-10A Large ground grid grounding resistance tester/Soil resistivity step voltage tester
Performance characteristics
1. Good power frequency equivalence of measurement. The test current waveform is sine wave, and the frequency is only 5Hz different from the power frequency, and two frequencies of 45Hz and 55Hz are used for measurement.
2, strong anti-interference ability. The instrument adopts different frequency method and modern software and hardware filtering technology, which makes the instrument have high anti-interference performance, and the test data is stable and reliable.
3, high precision. The basic error is only 0.005Ω, which can be used to measure large ground grids with small ground impedance.
4, can measure the current pile, voltage pile, grounding resistance, step voltage, contact voltage.
5, simple operation. Chinese menu operation, directly display the measurement results.
6, wiring labor is small, no need for large current line.
