Product Introduction:
YTC2830 Earth Grid Ground Resistance Tester adopts a new type of variable frequency AC power supply, and incorporates measures such as microprocessor control and signal processing, which effectively solves the anti-interference problem during testing, simplifies the test operation process, improves the accuracy and precision of test results, and greatly reduces the labor intensity and testing 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 uses an off-frequency anti-interference technology, enabling accurate measurement of data at 50Hz power frequency even in strong interference environments. The test current is 5A, which will not cause excessive potential rise of the grounding device during testing. Additionally, it has strong anti-interference capability, allowing measurements to be taken without power outage.
Product Aliases:Ground Grid Ground Resistance Tester, Earth Grid Ground Resistance Tester, Large Earth Grid Ground Resistance Tester.
Product Features:
1.Good power frequency equivalence. The test current waveform is sinusoidal, with a frequency only 5Hz different from the power frequency, using 45Hz and 55Hz for measurement.
2. Strong anti-interference capability. This instrument uses the off-frequency method combined with modern software and hardware filtering technology, giving it high anti-interference performance and stable, reliable test data.
3、High accuracy. The basic error is only 0.005Ω, making it suitable for measuring large earth grids with very low grounding impedance.
4、Powerful functions. It can measure current stakes, voltage stakes, grounding resistance, step voltage, and contact voltage.
5、Easy operation. Full Chinese menu-based operation, directly displaying measurement results.
6、Low wiring labor, no need for high-current cables.
