Transformer Turns Ratio Testing Meter

This tester is meant for three-phase transformers, particularly suitable for Z-winding transformers, rectifier transformers, and electrical systems railway Scott, inverse Scott balanced transformers. Input single phase power, and generate three or two phases of power by Internal power module, output to high voltage side, and then sample high voltage and low voltage at the same time, finally, the group, variation ratio, error, and phase difference are calculated.

It can be controlled by the computer through the USB port to upload, save, and print data. The instrument is very convenient to operate and is an ideal transformer ratio group polarity tester for power systems, transformer manufacturers, and railway electrical systems
