ETCR3000 Double Jaw Grounding Resistance Tester

Product Overview

A good grounding system is an important guarantee for the safe and reliable operation of power, telecommunications, and electrical equipment. The size of the grounding resistance is the basis for evaluating the quality of the grounding system. Accurate, fast, simple, and reliable methods for measuring grounding resistance have become an urgent need for technological progress in the field of lightning protection and grounding.
The ETCR3000 double jaw grounding resistance tester is suitable for telecommunications, power, meteorology, computer rooms, power distribution lines, iron tower transmission lines, gas stations, factory grounding grids, lightning rods, etc. This dual clamp multifunctional grounding resistance tester not only has the traditional function of using auxiliary electrodes to measure grounding resistance, but also has the unique function of measuring without auxiliary electrodes, which changes the traditional measurement principle and method of testing grounding resistance: using dual clamp non-contact measurement technology does not require auxiliary electrodes or isolating the grounding body from the load, achieving online measurement. Under conditions of single point grounding system and strong interference, the measurement method of using auxiliary electrodes can be adopted for measurement.

Product Features

1. Double clamp method/ground pile method dual measurement method: suitable for any grounding location, multiple or single point grounding, can be tested normally
2. Strong anti-interference ability: self-produced high-frequency current, thus filtering out harmonic interference currents such as 50Hz and 100Hz in the mains power. Even in a 500KV substation environment, it can accurately measure
3. The dual clamp multifunctional grounding resistance tester has a wide measurement range and high resolution: the range is from 0.01 Ω to 200 Ω, with a resolution of 0.01 Ω. It can also accurately measure grounding resistance below 0.7 Ω
4. Large jaw design: jaw diameter 50mm (standard configuration), suitable for using flat iron/steel as grounding lead, special jaw size can be customized according to customer requirements
5. Large capacity data storage: capable of storing 200 sets of measurement data
6. Easy to operate, single person assignment: fully Chinese operation interface, small size, light weight, explosion-proof portable case, easy to carry for field measurement
