Description:

The good or bad of conductivity of breaker(hereinafter referred to as switch) conductive circuit, play an important role in guarantee the safety operation of switch. The conductivity performance can be reflected by the value of conductive circuit resistance. For this reason IEC standard and manufacturers all required testing the circuit resistance, and also have prescribed index for the circuit resistance of each kind switch. Before, normally use double bridge. But, because the voltage and current value are very small, when there are impurities between dynamic and static contact or the contact got surface oxidation, the dispersivity of test data is larger. At the same time, the anti-interference performance of bridge is not good, so the national standard requires that must test with DC more than 100A.

The circuit resistance tester is a product developed by our company which in order to meet this regulations, and it was widely used in measurements of various switch’s contact resistance、circuit resistance, cable and wire、weld joint contact resistance.
