GDZRS-20A Three Phase DC Winding Resistance Tester
This DC resistance quick tester (hereinafter referred to as the DC winding resistance tester) is the latest generation product for measuring the DC resistance of transformers. It is optimized for measuring the DC resistance of three-phase windings of large-capacity transformers. The DC resistance of the three-phase windings of the transformer can be tested simultaneously. For the on-load voltage regulating transformer, it is not necessary to discharge the tap changer directly, and the measurement time is one third of the traditional single-phase measurement, which can greatly shorten the working time and labor intensity. The direct resistance meter adopts a large-screen liquid crystal display, all Chinese graphical interface, clear and intuitive, and the operation is very simple. And equipped with panel printer and large-capacity non-volatile memory, you can easily store and print the measurement results. The test data is stable, fast and repeatable, and it is the best choice for measuring the DC resistance of transformers on site.
