5A Ground Grid Earth Resistance Tester
Darui Electric recommends:
Product Overview:
5A Ground Grid Earth Resistance Tester is a software and hardware system mainly used for accurately measuring grounding characteristic parameters of large grounding grids, such as grounding impedance, grounding resistance, grounding reactance, field surface potential gradient, contact potential difference, contact voltage, step potential difference, step voltage, transfer potential, grounding down-conductor continuity resistance, and soil resistivity. It adopts point-by-point frequency conversion with strong anti-interference capability, enabling accurate measurement of data at power frequency 50Hz even in strong interference environments. The system has high output power (2-20KW), high voltage (0-1000V), and large output current (0-50A), which will not cause excessive potential rise of the grounding device during testing. Additionally, it possesses strong anti-interference ability, allowing measurement without power outage.
