Introduction
- GDZC Series Transformer DC Winding Resistance Tester is used for testing, installing and exchanging the semi-finished or finished transformer.
- GDZC Series Transformer DC Winding Resistance is applied to measure the DC resistance of inductance circuit such as power transformer coil, current transformer coil and it could be appplied to measure the cable resistance in 4-wire mode.
- GDZC Series Transformer DC Winding Resistance Tester is also a necessity for power department to do preventive trials.
- GDZC Series Transformer DC Winding Resistance Tester can effectively help you to find disfigurements in the manufacturing of transformer, such as the winding choosing, welding, loose joints, missing shares and hidden danger in the running.
- In order to meet the need of fast measurement of DC resistance, our company makes use of our technological advantage to develop the Micro Ohmmeter.
