Description
Overview
GAOTek ground earth resistance tester refers to the resistance encountered when current flows from the grounding device to the ground and then flows through the ground to another grounding body or diffuses towards a distance. The grounding resistance value reflects the good degree of contact between the electrical device and the ground and reflects the scale of the grounding network. Grounding can be divided into working grounding (zero line) Lightning protection grounding (ground wire) Protective grounding (ground wire) Screen grounding (ground wire) Anti-static grounding (ground wire)
