Automatic transformer ratio group tester is a new generation automatic transformer ratio tester developed by our company adopting modern electrode techniques. It is small volume, light weight, high precision, good stability. It uses the large screen display menu operation, friendly interface, can measure ratio group by one time.

1.Auto test the wire groups.
2.Auto change the groups.
3.Auto switch the phase sequence.
4.Auto change the measurement range.
5.Self calibrate the meters.
6.One time complete measurement. Auto cut off the measured voltage after the test finished.
7.Set the data, automatically save the test results, can review the historical data.
7.Only enter one ratio value when testing the loading transformer.
8.Auto calculate the relative error after input the standard ratio.
