This paper presents the analysis and simulation of occurrence and development of ferro­resonance in real electrical networks. The necessary and sufficient conditions for ferroresonance occurrence have been examined. It has been shown that in electrical networks this phenomenon is non-linear, so some special methods should be applied. A computer simulation has been performed to calculate the ferroresonance mode. During the analysis the application of the Jiles-Atherton model has allowed taking into account the hysteresis effect and improving the reliability of simulation. The ways of pre­venting ferroresonance phenomena in electrical networks at open-phase operating conditions are presented.
