TTR-I Single Phase and Three Phase Transformer Turns Ratio Tester

Introduction:

It is designed according IEC76-1 and IEC60044.

It can be applied to test the turns ratio and group vector of single or three phase transformer.

The connection group of three phase transformer also can be calculated with the ratio.

All parameters can be measured in one test for three phase transformer.
