What are the practical limitations in achieving a transformer with zero magnetizing current? How does the magnetizing current affect the design of transformer bushings and tap changers?

The knee point is defined as the voltage at which a 10% increase in applied voltage increases the magnetizing current by 50%. Figure 2 shows the magnetizing current waveform when the duty ratio fluctuates. The PSFB converter transfers energy to the secondary side from the primary side, ... The piecewise-linear approximation of power transformer magnetization characteristic, allow to obtain the amplitude value of magnetizing inrush current caused ... As we discussed, the magnetizing current is the current drawn by the transformer for setting up magnetic flux in the core. Therefore, the magnetization current, ... May 3, 2013 ... With an induction motor, there is no permanent field: instead, the magnetic field is developed by current flowing in the stator winding. This ...
