Product introduction

Transformer DC Resistance Tester also named Low Resistance Ohmmeter, It is a necessary testing project for transformer transition, overhauling and changing tap switch, it is also an important detecting project after fault. Transformer DC Resistance Tester is a quick test equipment for testing transformers, generators, motors, lines and other DC resistance.

Transformer DC Resistance Tester is integrated high-precision power supply and DC resistance test in a whole as a new instrument, which not only maintain the original advantage but also greatly reduces the size and weight of the instrument and expands the measurement range. The instrument adopts the high-performance single-chip microcomputer control, simple operation, easy to carry, fast testing speed, high precision, good retest, strong anti-interference capability, automatically complete the judgment of steady flow, data acquisition and processing and display resistance, can accurately complete the measurement of transformer dc resistance, This instrument is the best testing equipment for power plant, power supply enterprises, medium and large-sized power transformer manufacturing industries and enterprises.

According to different level of current, Wuhan Nanrui Electric Co., LTD has developed six types of Transformer DC Resistance Tester, they are NRZDC-5A, NRZDC-10A, NRZDC-20A, NRZDC-40A, NRZDC-50A, NRZDC -100A, etc.

Alternative name

DC Resistance Rapid Tester, Transformer DC Resistance Tester, Transformer DC Resistance Rapid Tester, Transformer Winding DC Resistance Tester, Inductive Load DC Resistance Rapid Tester, Inductive Load DC Resistance Tester, Sensual loaded DC resistance tester.

The Characteristics of the products
