3A Ground Grid Earth Resistance Tester - Yangzhou Darui
Darui Electric recommends this product for you
3A Ground Grid EarthResistance Tester 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. This instrument adopts heterodyne anti-interference technology, which can accurately measure data at 50Hz under strong interference environments. The maximum test current is 5A, which will not cause excessive potential on the grounding device during testing. It also has strong anti-interference capability, so measurements can be performed without power outage.
Product aliases:
Ground grid earth resistance tester, variable frequency high current ground impedance tester, large ground grid grounding impedance test system, grounding device characteristic parameter test system, ground grid grounding impedance tester, grounding impedance tester, variable frequency anti-interference grounding impedance tester, substation grounding grid grounding characteristic parameter tester, 3A ground grid earth resistance tester, variable frequency high current multifunctional grounding impedance tester, etc.
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 heterodyne 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 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.
