GDBC-901 High Precision Automatic Transformer Turn Ratio Meter



This model transformer TTR meter suits for D and Y connection power transformers.


The automactic transformer turn ratio tester weighs (<7 KG) less than most commercially available instrument. A rugged and robust design makes this TTR well suited for use in a variety of harsh environments. The TTR is also particularly suited for testing in power transformer manufacturing environments where testing of complex, three-phase substation power transformers can be performed quickly while minimizing the possibility of errors.
