Real-life situations that can give rise to ferroresonance
Ferroresonance in networks - Modeling and applications to circuit typology

Ferroresonance can occur in single-phase or polyphase circuits. The circuit configurations that give rise to it are fairly well known and listed at [5][22]. A distinction is made between "series" configurations, where a capacitor is in series between the non-linear element and the voltage source, and "parallel" configurations, where the capacitor involved in the ferroresonance phenomenon is in parallel with the non-linear element. The following are examples of ferroresonance that may occur on a power transmission or distribution network:

• single-phase series circuit with voltage transformer ;

• voltage transformer capacitor (TCT) ;

• spur or antenna station on a double terne line;

• resumption of service or voltage recovery on a long...
