Megger TTRU1-Basic Single Phase Transformer Turns Ratiometer

Power through transformer electromechanical tests with the new TTRU1, the latest handheld transformer turns ratiometer from Megger. Perform routine polarity validation and turns ratio tests on power, distribution, and instrument transformers guided by colour-coded leads, clamps, and customisable on-screen vectors that match the transformer nameplate under test. In addition to turns ratio tests, the TTRU1 adds go/no-go short circuit, open circuit, and inductance test capabilities. The easy to follow setup ensures the right result the first time - just click start and perform over 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.

TTR - Turns ratio testing - 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.

Additive/Subtractive polarity recognition - Polarity recognition provides confidence in transformer results by performing vector group validation during every test. Results on screen show if the connected distribution transformer is additive or subtractive.

Excitation current - Included with the TTR test, the excitation current test is extremely useful in locating problems such as defects in magnetic core balance, magnetic core structure, shifting windings, failures in the turn-to-turn insulation, or problems in tap changers.
