The HYG-5A DC resistance tester is an indispensable test item for Transformers after handover, overhaul, and change of splitter switches. Under normal circumstances, measuring the DC resistance of transformer windings and high-power inductive equipment by traditional methods(bridge method and pressure drop method) is a time-consuming and laborious task. In order to change this situation, shorten the measurement time and reduce the workload of the test personnel, the company has developed a DC resistance tester(hereinafter referred to as direct resistance meter). It adopts the new power supply technology, which has the characteristics of stable performance, rapid measurement, compact volume, convenient use, high measurement accuracy, and good data repeatability. It is an ideal equipment for measuring Transformer windings and DC resistors of high-power inductor equipment.
