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.

Product features:

1, output current 10A, strong anti-interference and output current delay function;

2, constant current output, no manual adjustment, no short circuit zero adjustment;

3, the test efficiency is extremely high, there is no charge and discharge process, and the measurement of a point can be completed in only 2 seconds;

4, the operation is simple, and the measurement result can be obtained only by pressing the measurement key;

5.DC resistance measurement eliminates the influence of test resistance and measured resistance;

6. The panel and chassis are integrated, with good seismic performance.
