Product Description

Single Phase or Three Phase Current Transformer Turns Ratio TTR Meter

Introduction:

1. TTR-I Transformer Turns Ratio TTR Meter is designed according IEC76-1 and IEC60044. 
2. TTR-I Transformer Turns Ratio TTR Meter can be applied to test the turns ratio and group vector of single or three phase transformer.
3. The connection group of three phase transformer also can be calculated with the ratio.
4. All parameters can be measured in one test for three phase transformer.
