BZC-50A Transformer DC Resistance Tester

The DC resistance test of transformer windings 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, a DC resistance tester (hereinafter referred to as DC resistance tester) is used.BZC-50A Transformer DC Resistance TesterAdopting new power technology, it has the characteristics of stable performance, fast measurement, compact 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.

BZC-50A Transformer DC Resistance TesterMeets the requirements of the national standards GB6587-86 "General Principles for Environmental Testing of Electronic Measuring Instruments" and GB6593-86 "Quality Verification Rules for Electronic Instruments".
