Product Introduction:
The YTC2830 earth network grounding resistance tester adopts a new type of variable frequency AC power supply and measures such as microcomputer processing control and signal processing, which effectively solves the anti-interference problem during the testing process, simplifies the experimental operation process, improves the accuracy and precision of the test results, and greatly reduces the labor intensity and testing cost of the testing personnel.
This instrument is suitable for testing the power frequency grounding impedance, contact voltage, step voltage, and other power frequency characteristic parameters of various grounding devices, as well as soil resistivity. Multi purpose models for measuring substation grounding (4 Ω), hydro thermal power plants, microwave stations (10 Ω), and lightning rods (10 Ω).
This instrument adopts cross frequency anti-interference technology, which can accurately measure data at the power frequency of 50Hz in strong interference environments. The test current is 5A, which will not cause the potential of the grounding device to be too high during testing. At the same time, it also has strong anti-interference ability, so it can be measured without power outage.

Product nickname:Grounding resistance tester for ground grid, grounding resistance tester for ground grid, and large-scale grounding resistance tester for ground grid.

Product features:
1The measured power frequency equivalence is good. The test current waveform is a sine wave, with a frequency difference of only 5Hz from the power frequency. Two frequencies, 45Hz and 55Hz, are used for measurement.
2Strong anti-interference ability. This instrument adopts the frequency difference method for measurement, combined with modern software and hardware filtering technology, making the instrument have high anti-interference performance and stable and reliable test data.
3High precision. The basic error is only 0.005 Ω, which can be used to measure the earth network with very small grounding impedance.
4Powerful functionality. Can measure current pile, voltage pile, grounding resistance, step voltage, and contact voltage.
5Easy to operate. Fully Chinese menu style operation, directly displaying measurement results.
6Low wiring workload, no need for high current wires.
