Global InformationFerroresonance in electricity networks information
Ferroresonance or nonlinear resonance is a rare[1] type of resonance in electric circuits which occurs when a circuit containing a nonlinear inductance is fed from a source that has series capacitance, and the circuit is subjected to a disturbance such as opening of a switch.[2] It can cause overvoltages and overcurrents in an electrical power system and can pose a risk to transmission and distribution equipment and to operational personnel.[3]
Ferroresonant effects were first described in a 1907 paper by Joseph Bethenod.[3][4] The term ferroresonance was apparently coined by French engineer Paul Boucherot in a 1920 paper, in which he analysed the phenomenon of two stable fundamental frequency operating points coexisting in a series circuit containing a resistor, nonlinear inductor and a capacitor.[5][6]
