Product Introduction

   The DC resistance test of transformer windings is an essential test item after transformer handover, overhaul, and tap-changer adjustments. Traditionally, measuring the DC resistance of transformer windings and high-power inductive equipment using conventional methods (such as bridge method and voltage drop method) is time-consuming and labor-intensive. To address this issue, reduce measurement time, and alleviate the workload of test personnel, our company has developed the DC Resistance Fast Tester (hereinafter referred to as the DC Resistance Tester).

   It adopts advanced power supply technology, offering stable performance, fast measurement, compact size, ease of use, high measurement accuracy, and excellent data repeatability. It is an ideal device for measuring the DC resistance of transformer windings and high-power inductive equipment.
