3-Phase Transformer Turns Ratio Test Sets

The TTR300 Series of three-phase transformer turns ratio test sets is designed to measure the turns ratio of power, instrument, and distribution transformers in a substation or manufacturing environment. A rugged and robust design makes these instruments well suited for use in a variety of harsh environments. Our leads are specially designed to provide the necessary flexibility needed in cold weather.

• Store and download test results in XML format, via RS-232, Ethernet or USB ports (depending on model)
• Works in the presence of high interference/ high voltage
• Capable of measuring phase-shifting transformers
• Highest ratio measurement (45,000:1)
• Displays % error vs. name plate with pass/fail limits
• Capability for automatic vector detection when testing via PowerDB
