Ferroresonance and Transformer Connections are related as such that the latter is a significant factor to the occurrence of the former during loss of phase or open phase conditions. There are certain transformer configurations that are more susceptible to ferroresonance. Generally, ferroresonance phenomenon becomes highly probable if the primary windings of the three-phase transformer are ungrounded.
