New Design-GDB-IV Transformer Turns Ratio Tester(Excitation Current Test) with Lithium Battery

GDB-IV Transformer Turns Ratio Tester is suitable for measuring variable ratio phase of power transformers, phase-shift rectifier transformers, Scott transformers, reverse Scott transformers, etc.

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.

It can also use to measure excitation current of transformer.

The device has a built-in lithium battery for long-term power supply, which is convenient for field use.
