KDRS-10A Three-channel Transformer DC Resistance Tester is the latest generation product for measuring transformer DC resistance, optimized for measuring three-phase winding DC resistance of large capacity transformers. It enables simultaneous testing of the three-phase windings of transformers. For on-load tap-changing transformers, it can adjust the tap switch directly without discharging, reducing the measurement time to one-third of traditional single-phase measurements, significantly shortening work time and labor intensity. The DC resistance meter features a large screen LCD display with a full Chinese graphical interface, clear and intuitive, with very simple operation. It is also equipped with a panel-type printer and a large-capacity non-volatile memory, making it convenient to store and print measurement results. The test data is stable, fast, and has good repeatability, making it an excellent choice for on-site transformer DC resistance measurement.
