  • 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...
