Megger TAU3

The multifunction TAU3 streamlines transformer testing with a one-time connection for all tests, reducing reliance on multiple instruments and minimising testing time, helping you maximise productivity for fast and accurate maintenance decisions. In addition to routine polarity validation, turns ratio, winding resistance, and demagnetization tests, the TAU3 offers short-circuit impedance and efficiency tests with the same one-time lead connection. Guided by colour-coded leads and clamps with on-screen vectors that match the transformer nameplate, the easy-to-follow setup ensures the right result the first time…just click ‘start’ and let the patent-pending internal shorting and lead compensation do the work!
