GDBC-901 High Voltage Transformer Turns Ratio Tester , TTR Meters
The Automatic Transformer Turn Ratio TTR Tester is designed to measure the turns ratio of power, instrument, and distribution transformers in a substation or manufacturing environment.
It weighs (<7 KG) less than most commercially available instrument. A rugged and robust design makes this TTR test set well suited for use in a variety of harsh environments.
The phase transformer turn ratio tester 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.
