Abstract :
The mathematical model of electromagnetic voltage transformer has been developed. The ferromagnetic properties of the transformer are described by using Jiles-Atherton model in which the influence of magnetization reversal speed on coercive force value was taken into account. This mathematical model allows considering the phase-to-phase interaction during ferroresonance. The influence of switchgear parameters on ferroresonance beginning and behavior was shown.
