Transformer winding analyser TAU3

About Transformer winding analyser TAU3

TAU3, the three-phase transformer winding analyser. Perform polarity validation, turns ratio, winding resistance, and demagnetization tests with the same onetime lead connection. TAU3 is designed to test all power, instrument (CTs and PT/VTs), and distribution transformers. With minimal input from the user, the TAU3 uses patent pending step up excitation to deliver the required AC/DC voltage and current to obtain accurate results Find vector / polarity recognition, Features includes TTR - Turns ratio testing, Excitation current, Phase angle deviation, Magnetic balance, Winding resistance, Automatic adaptive demagnetization, OLTC make before break continuity, One-touch OLTC
