The grounding resistance testerunder UHV power can help many power workers conduct various power tests more conveniently.

The grounding resistance testeris a resistance measurement device mainly used for measuring grounding resistance, soil resistivity, grounding voltage, AC current, and leakage current in power, telecommunications, meteorological oil fields, construction, lightning protection, industrial electrical, and other fields. Equipment. But different models or environments use different resistance testers.

There are several types of grounding resistance measuring instruments, including clamp type (double clamp type), large grounding grid grounding, digital, etc. They not only differ in product characteristics, but also in measurement methods. People usually think that as long as resistance can be measured, but in fact, if mismatched measuring instruments are chosen, not only will it be impossible to accurately measure resistance, but it will also waste unnecessary time and labor costs. Let's take a look at various resistance testers together!

The dual clamp grounding resistance tester is designed and manufactured for on-site measurement of grounding resistance, soil resistivity, grounding voltage, leakage current, AC current, and DC resistance. Can be used to measure grounding systems for large grounding down conductors. It can flexibly and accurately measure any grounding resistance value under various complex grounding conditions such as single point and mesh grounding. When measuring parallel grounding, there is no need to disconnect any parallel grounding electrodes, greatly improving the convenience of measurement.

A large grounding resistance tester is a high-precision testing instrument used in the field of substation grounding resistance and related parameter testing. A large number of on-site tests and user applications have shown that the resistance tester is an ideal instrument for measuring the characteristic parameters of large and medium-sized grounding grids. It is accurate, stable, and reproducible when testing grounding grids in harsh electromagnetic environments. Operating a substation.

Intelligent insulation resistance tester is suitable for testing various high-voltage equipment, including switchgear, transformers, reactors, capacitors, motors, generators, and cables, to measure insulation resistance (IR), absorption ratio (DAR), and polarization index (PI).
