NRZDC Transformer DC Resistance Tester (5A~10A)

Transformer DC Resistance Tester also named Transformer Winding Resistance Tester 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 NANR Electric Co. LTD has developed several types of Transformer DC Resistance Tester they are NRZDC-5A NRZDC-10A NRZDC-20A NRZDC-40A NRZDC-50A NRZDC -100A etc.

Alternative name

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