TTRU1-BASIC Single-Phase Handheld Turns Ratiometer (37.5 V AC)

Handheld Transformer Turns Ratiometer (37.5V Max Induced Voltage)

Power through transformer electromechanical tests with the new TTRU1, the latest handheld transformer turns ratiometer from Megger. Perform routine polarity validation and turn ratio tests on power, distribution, and instrument transformers.

When compared to other single-phase turns ratio test instruments, the TTRU1 is easier to use as you don't need to know the proper test voltage to obtain a valid test result.

The TTRU1 uses the latest technological advancements, providing safe, repeatable, and reliable results.
