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.
