  • GDZRS-20A Three Phase DC Winding Resistance Tester

    GDZRS-20A Three Phase DC Winding Resistance Tester

    This device is new generation product, which is optimal designed for measuring big capacity transformer three phase winding DC resistance. It tests transformer three phase winding DC resistances at the same time. Its no need to discharge for on-load variable transformer, just adjust tap switch directly. The measurement time is 1/3 of tradition single phase measurement, that working time and labor intensity is shorten. It use big screen LCD display, clear and visual, easy operation. Meanwhile, it equip with panel printer and big capacity memory that is easy to get printing result and convenient to storage data. Stable data, fast testing and good repeatability, with that is the best choice for transformer DC resistance on-site measurement.

  • GDB-II  Transformer Turns Ratio Tester

    GDB-II Transformer Turns Ratio Tester

    According to IEC and relevant national standards, the transformer ratio test is a must-do item during the production, user handover, and overhaul test of power transformers. This can effectively supervise the quality of the transformer products during delivery and use, and prevent short circuits, open circuit, wrong connection between transformer turns, and internal failure or contact failure of the regulator switch.

    For this reason, the ratio tester GDB-II developed and produced by our company makes the operation easier, complete functions, stable and reliable data, and greatly improves the test speed according to the user’s on-site use requirements on the original basis. It meets the needs of various large, medium, and small oil transformer ratio tests.
