Abstract: Ferroresonance has more damaging effects on transformers and other equipments in distribution networks such as oscillating over voltages and over currents, distortion in voltage and current waveforms, transformer heating, loud noise due to magnetostriction and mal-operation of the protective devices. In this paper we effort to study and assess various impacts of ferroresonance phenomenon on operating performance of power transformers in a 20kV real network and to investigate ways to mitigate the effects of such phenomenon. Three-phase core-type transformers are used in the study. The results of the technical investigation showed that ferroresonance can cause dangerous over-voltages and over-currents in three-phase core type transformers.
