    Product Details of UHV-10A Transformer DC Winding Resistance Tester


    Product Introduction:

    The DC resistance test of transformer windings is a critical inspection item following transformer commissioning, major overhauls, and tap changer adjustments. Traditional measurement methods, such as the bridge method and the voltage drop method, are often time-consuming and labor-intensive when measuring the DC resistance of transformer windings and high-power inductive equipment. To address this limitation, shorten testing time, and reduce the workload of operators, our company has developed a DC Resistance Fast Tester (hereinafter referred to as the DC Resistance Tester).

    Utilizing advanced power technology, this instrument features stable performance, rapid measurement, compact design, user-friendly operation, high accuracy, and excellent data repeatability. It serves as an ideal solution for measuring the DC resistance of transformer windings and high-power inductive devices.
