Transformer Winding Resistance Tester Micro Ohm Meter DC Winding Resistance Test Set
GDZC Series Transformer Winding Resistance Tester is suitable for large-scale transformer above240MVA in temperature rising tests.
840MVA transformer low-voltage direct-resistance tester completed within 2 minutes and the data is stable and accurate.
Dual-channel shows the measurement data at the same time.
Each interval of 60 seconds automatically print data.
Equipped with temperature conversion software, curve waveforms.
GDZC Series Transformer Winding Resistance Tester is used for testing, installing and exchanging the semi-finished or finished transformer.
GDZC Series Transformer Winding Resistance Tester is also a necessity for power department to do preventive trials.
GDZC Series Transformer 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.
