TTR-I Power Transformer Turns Ratio TTR Meter For Three Phase Transformer Testing
Introduction:
TTR-I Power Transformer Turns Ratio TTR Meter is designed according IEC76-1 and IEC60044.
TTR-I Power Transformer Turns Ratio TTR Meter 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.
