Product Introduction:
YTC2830 Ground Grid Ground Resistance Tester adopts a new type of variable frequency AC power supply, and adopts measures such as microprocessor control and signal processing, which effectively solves the anti-interference problem during the testing process, simplifies the test operation process, improves the accuracy and precision of test results, and greatly reduces the labor intensity and test cost for testers.
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. It can measure substation ground grids (4Ω), thermal and hydro power plants, microwave stations (10Ω), and lightning rods (10Ω) as a multi-purpose model.
This instrument adopts the heterodyne anti-interference technology, which can accurately measure data at 50Hz under strong interference environments. The test current is 5A, which will not cause excessive potential rise of the grounding device during testing. At the same time, it also has strong anti-interference capability, so measurement can be carried out without power outage.

Product Features:
1.Good power frequency equivalence. The test current waveform is a sine wave, and the frequency differs from the power frequency by only 5Hz, using 45Hz and 55Hz for measurement.
2. Strong anti-interference capability. This instrument uses the heterodyne method for measurement, combined with modern software and hardware filtering technology, giving the instrument high anti-interference performance and stable and reliable test data.
3、High accuracy. The basic error is only 0.005Ω, making it suitable for measuring large ground grids with very small grounding impedance.
4、Powerful functions. It can measure current stake, voltage stake, grounding resistance, step voltage, and contact voltage.
5、Simple operation. Full Chinese menu-based operation, directly displaying measurement results.
6、Low wiring labor, no need for high-current cables.
