Transformer Turns Ratio Tester(TTR Tester)

  • 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.

  • GDB-P Auto Transformer Turns Ratio Tester

    GDB-P Auto Transformer Turns Ratio Tester

    According to IEC and the relevant national standards, transformer turns ratio test is a necessary project in the process of power transformer production, user handover and maintenance test.

  • GDB-D Transformer Turn Ratio Tester

    GDB-D Transformer Turn Ratio Tester

    GDB-D Transformer turn ratio tester is designed for three phases transformer in power system and especially for Z type winding transformer and other transformers with relatively large no-load current. 

  • GDB-H Handheld Automatic Transformer Turns Ratio Tester

    GDB-H Handheld Automatic Transformer Turns Ratio Tester

    It can accurately measure turns ratio, group and phase angle, which is suitable for all kinds of transformers such as Z type transformers, rectifier transformers, electric furnace transformers, phase-shifting transformers, traction transformers, scott and invert-scott transformers.

  • GDB-IV Three Phase Transformer Turns Ratio Tester

    GDB-IV Three Phase Transformer Turns Ratio Tester

    The internal power module in the tester generates the three-phase power or two-phase power, which is output to the high voltage side of the transformer. Then the high voltage and low voltage are sampled at the same time. Finally, the group, ratio, error, and phase difference are calculated.
