How to test poor contact with harness continuity tester
The reliable and effective connection between the grounding downlead and the grounding grid of power equipment is the fundamental guarantee for the safe operation of the equipment. Grounding down lead is the connection part between power equipment and grounding grid. During the long-term operation of power equipment, due to moisture and other factors, the joints may be corroded or even broken, resulting in an increase in the resistance of the connection point between the grounding down lead and the main grounding network, which can not meet the requirements of power regulations. The tester is used to measure the on-resistance value between the grounding downlead of each power equipment in the substation.
