How can the measurement and analysis of magnetizing current be used as a diagnostic tool during transformer maintenance?

The method is based on magnetization current, harmonic content and power factor evaluated of the transformer no-load current with high magnetic flux density ... As the sinusoidal input voltage transitions from positive to negative, the magnetizing current will respond in kind, driving the flux density developed in the ... The knee point is defined as the voltage at which a 10% increase in applied voltage increases the magnetizing current by 50%. Jun 9, 2013 ... The secondary current, divided by the turns ratio, plus the magnetising current, is the current the transformer takes from the supply. Whether ...
