Reliable and effective connection between grounding lead and ground network of power equipment is the fundamental guarantee for safe operation of equipment. Grounding lead is the connection between power equipment and ground network. During the long-term operation of power equipment, the connection may be affected by dampness and other factors, resulting in node corrosion, or even breakage, which leads to the increase of resistance of the connection point between grounding lead and main ground network, thus failing to meet the requirements of power regulations, making the equipment unsafe in operation, and in serious cases. It will cause the equipment to lose ground.

This tester is a highly automated portable tester developed by our company. It is specially used to measure DC resistance of portable short-circuit grounding wire and personal protection grounding wire.
