The DC resistance test of transformer windings (10A DC resistance tester) is an essential 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 10A DC resistance rapid tester (hereinafter referred to as the DC resistance tester). The 10A DC resistance tester adopts a new power supply technology, which has the characteristics of stable performance, fast measurement, small size, easy use, high measurement accuracy, and good data repeatability. It is an ideal device for measuring the DC resistance of transformer windings and high-power inductive equipment.
