ZC-1A DC Resistance Tester

ZC-1A DC Resistance Tester

It is a test item for transformers after handover, major repairs, and changes to tap changers. Under normal circumstances, measuring the DC resistance of transformer windings and high-power inductive devices using traditional methods such as bridge method and voltage drop method is a time-consuming and labor-intensive task. In order to change this situation, shorten measurement time, and reduce the workload of testers, our company has developed a DC resistance rapid tester (hereinafter referred to as the DC resistance tester).
