KVZR-20S Three Phase Transforerm DC Winding Resistance Tester

Overviews

Transformer DC Winding Resistance Tester , also termed transformer ohmmeter, is the newest product for DC resistance measurements of transformers. It’s particularly designed for the DC resistance of three-phase windings in high-capacity transformers, allowing for simultaneous testing of all three phases. With this device, there is no need to discharge the tap changer for on-load voltage regulating transformers, and the measurement process is three times faster than the traditional single-phase approach, thus greatly reducing work time and effort. The tester features a large-screen LCD with an intuitive graphical interface, simplifying operation. It includes a panel printer and extensive non-volatile memory for straightforward storage and printing of results. The device ensures stable, rapid, and consistent test data, making it an excellent choice for on-site transformer DC resistance testing.
