Ground Grid Earth Resistance Tester - Yangzhou Darui
Darui Electric recommends for you
Main Features:
1.Ground Grid Earth Resistance Tester has good power frequency equivalence. The test current waveform is a sine wave, and the difference between the frequency and the power frequency is only 5Hz. Measurements are made using two frequencies: 45Hz and 55Hz.
2、Strong anti-interference capability against ground voltage. This instrument uses the heterodyne frequency method, combined with modern software and hardware filtering technology, giving the instrument high anti-interference performance and stable and reliable test data. The error caused by a 20V power frequency interference voltage is only 0.002Ω.
3、High precision. It can be used to measure large ground grids with very small grounding impedance.
4、Powerful functions. It can measure all characteristic parameters of the grounding device as specified in relevant standards. Not only can it measure grounding impedance, but it can also measure the resistance component and reactance component.
5、Can measure on-site interference, making it convenient for users to estimate measurement errors.
6、Equipped with a disconnection alarm function to avoid incorrect measurements.
7、Simple operation. Full Chinese menu-style operation, directly displaying measurement results.
8、Can save 50 sets of measurement data, and comes with a built-in micro printer for on-site printing of measurement results.
9、Low wiring labor, no need for high-current cables.
10、This instrument is small in size, light in weight, and easy to carry.
