Overview

The ZSR20D/ZSR40D/ZSR50D series grounding wire conductivity tester is used to measure the resistance value of the grounding wire of power equipment in substations. It can effectively detect the increase in resistance value caused by various reasons in the lead resistance between electrical equipment and the ground grid, so as to avoid equipment loss operation.
