When it comes to Transformer winding resistance measurement on three-phase power transformers and autotransformers, GDZC-SERIES offers some of the most technically advanced instruments with LCD display in the market. Both models are capable of testing six transformer windings with a one-time cable connection, as well as three-phase automatic transformer demagnetization.
The stored magnetic energy is safely automatically discharged at the end of the test. The built-in tap changer control unit enables automated test mode, where the instrument operates the tap changer without operator input and records winding resistance results based on pre-selected stabilization criteria. This option makes the operator’s job significantly easier.
Introduction:
l GDZC Series Transformer Winding Resistance Tester is used for testing, installing and exchanging the semi-finished or finished transformer.
l GDZC Series Transformer Winding Resistance Tester is also a necessity for power department to do preventive trials.
l 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.
l 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;
Features:
l GDZC Series Transformer Winding Resistance Tester is suitable for large-scale transformer above240MVA in temperature rising tests.
l 840MVA transformer low-voltage direct-resistance tester completed within 2 minutes and the data is stable and accurate.
l Dual-channel shows the measurement data at the same time.
l Each interval of 60 seconds automatically print data.
l Equipped with temperature conversion software, curve waveforms.
