TTRU1 handheld transformer turns ratiometer

The TTRU1 is the latest handheld transformer turns ratiometer from Megger. In addition to routine polarity validation and turns ratio tests, the TTRU1 can measure short-circuit impedance (leakage reactance) with the same one-time connection.

Guided by colour-coded leads, clamps, and customisable on-screen vectors that match the transformer nameplate under test, the easy-to-follow setup ensures the right result the first time.

Perform up to 1000 turns ratio tests on a single NiMH AA battery charge. When it’s time to recharge the batteries, connect to any standard USB wall charger, or connect to your PC. When connected to the PC, TTRU1-EXP results can be downloaded, and the user guide and data sheet can also be accessed.
