Case 1: Magnetizing inrush current:
In this section of simulation, when the primary side CB1 is closed at 0.1 sec, only the inrush
current flows in the primary circuit of the power transformer and no current passes through
the power transformer to the secondary side as shown in Fig. 13. The harmonic comparator
shows in Fig. 14 that the value of the 2nd harmonic is higher than 0.3 of the fundamental
component.
