  • HTZZ-1A Transformer Resistance Tester

    DC resistance measurement of transformer winding is an essential test project during transformer transfer, repair and changing tapping switch. Measuring DC resistance of transformer winding, you can check out weld or connection quality of down-lead, the winding inter-turn short circuit or open circuit, and whether tap-changer is well contacted. In the previous it is generally to use QJ44 double bridge to measure ...

  • HTZZ-10A Transformer DC Resistance Tester

    When the transformer is cross-connected, overhauled or some of its switches are changed, direct current resistance testing of the transformer winding is a must. In general, to measure the transformer winding or large power output inductor equipment, the traditional electrical bridge method and pressure drop method require much time and energy. Thus, to shorten the measurement time and reducing the workload of...
