Abstract :
The instant of switching on ac supply voltage plays an important role in formation of ferroresonance. Simulation of ferroresonance is worked out on each electrical degree over 0° to 360° of the sinusoidal supply voltage with varying magnitude of initial magnetization. The resulting ferroresonance over-voltages, currents are presented and analyzed identifying critical features.
