XHEP701A Earth resistance Tester
Product Introduction
XHEP701A grounding grid resistance tester can measure substation grounding network (4Ω), water and thermal power plant, microwave station (10Ω), lightning rod (10Ω) multi-purpose machine, adopts new frequency conversion AC power supply, and adopts computer processing control and signal processing measures. It solves the anti-interference problem in the test process very well, simplifies the test operation process, improves the accuracy and accuracy of the test results, and greatly reduces the labor intensity and test cost of the test personnel.
Main Feature
1. The measured power frequency equivalence is good. The test current waveform is a sine wave, and the frequency is only 5 Hz from the power frequency, and is measured using two frequencies of 45 Hz and 55 Hz.
2. Strong anti-interference ability. The instrument adopts the different frequency method to measure, and with the modern software and hardware filtering technology, the instrument has high anti-interference performance, and the test data is stable and reliable.
3. High precision. The basic error is only 0.005 Ω and can be used to measure large ground grids with low ground impedance.
4. Powerful. It can measure current pile, grounding resistance of voltage pile, grounding resistance of grounding grid, on-resistance and soil resistivity.
5. easy to use. Full Chinese menu operation, directly showing the measurement results.
6. The wiring is labor intensive and does not require a large current line.
