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

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 ferromagnetic core inside an electrical device – primarily a voltage transformer or an unloaded power transformer – operates in the saturated condition, under which inductance has become a non-linear element. In practice, ferro resonance can be triggered even by a temporary introduction of core
