  • 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.
