Darui Electric recommends for you
In addition to the functions of the dual-clamp multifunctional ground resistance tester, it also has the unique function of measuring without auxiliary ground electrodes, which changes the traditional measurement principles and methods of ground resistance testing: using dual-clamp non-contact measurement technology, no auxiliary ground electrodes are needed, and there is no need to isolate the grounding body from the load, enabling online measurement. Under conditions such as single-point grounding systems or strong interference, measurement can be carried out using the auxiliary ground electrode method.
Features of the dual-clamp multifunctional ground resistance tester:
1. Dual measurement modes: dual-clamp method / ground stake method:
Suitable for any grounding site, whether multi-point or single-point grounding, it can test normally;
2. Strong anti-interference capability:
It generates high-frequency current itself, thereby filtering out harmonic interference currents such as 50Hz and 100Hz from the mains, and can measure even in a 500KV substation environment;
3. Wide measurement range and high resolution of the dual-clamp multifunctional ground resistance tester:
The range is from 0.01Ω to 200Ω, with a resolution of 0.01Ω, and it can accurately measure ground resistance below 0.7Ω;
4. Large clamp jaw design:
The clamp jaw diameter is 50mm (standard configuration), suitable for situations where flat iron/steel is used as the grounding lead; special clamp jaw sizes can be customized according to customer requirements;
5. Large capacity data storage of the dual-clamp multifunctional ground resistance tester:
It can store 200 sets of measurement data;
6. Simple operation, single-person operation:
Full Chinese operation interface, small size, light weight, explosion-proof portable case, convenient for field measurement.
