NRZDC-S10A Three-phase DC Resistance Tester

DC Resistance Tester is a transformer DC resistance measurement of the latest generation of products for the measurement of large capacity transformer winding DC resistance and optimization design. Three-phase winding DC resistance of transformer was tested at the same time. The on-load transformer cannot discharge directly regulating tap switch the measurement time is the traditional single-phase measured 1/3 can greatly shorten the labor time and intensity. DC resistance tester with large LCD display full English interface clear and intuitive the operation is very simple. And equipped with panel printer and large capacity non-volatile memory can store and print the measuring results. Stable test data fast good repeatability is the best choice of DC resistance tester of transformer.

Product characteristics
