The DC resistance test of transformer windings is an indispensable test project after Transformer is transferred, overhauled and switched. 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 testers, the company has developed the HYG-5A DC Resistance Rapid Test Instrument(hereinafter referred to as the Direct Resistance Instrument). 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.
