The Megger TTR310E Three-Phase Transformer Turns Ratio Test Set 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 this instrument well suited for use in a variety of harsh environments, with leads specially designed to provide the necessary flexibility needed in cold weather.

The TTR310E is ideal for use by power transformer manufacturers. The test set's unique testing procedures and storage capability allows an operator to set up and test difficult three-phase transformers (with multiple tap changers and bushing CTs) in a fraction of the time that it used to take with other TTRs. This test also includes a pass/fail limit of individual ratios

Megger TTR310E Three-Phase Transformer Turns Ratio Test Set features:

• Fully automatic operation (either stand-alone or remote-control)
• Built-in RS-232 port and optional thermal spool-paper printer allows for printing of test results, while in the field, and without the use of an external computer
• Built-in capability for storing test results into internal memory in an open data format for direct input into Excel or XML format via PowerDB LITE
