Ferroresonance Phenomena for Voltage Transformer failure – Simulation & Analysis using EMTP and Mitigation Technique


Abstract
Ferroresonance is an oscillating phenomenon between a non-linear inductance and a capacitor that can results in highly distorted over voltages and overcurrent. Ferroresonance phenomenon occurs when a ... see more
