Ferroresonance Prevention Tutorials deal with strategies that electric utilities and end-users could implement to minimize occurrence of the power quality phenomenon. These practices are based from the fact that ferroresonance usually happens with lightly loaded three-phase transformer, having one or two phases open either intentionally or accidentally. Common strategies for managing ferroresonance include: Preventing open phase condition, limiting overvoltages, damping resonance with secondary load, limiting cable length, switching at transformer terminals and grounding transformer primary.
