In order to restrain ferroresonance in coupling capacitor voltage transformers (CCVT), two kinds offerroresonance suppression circuits (FSCs) , are proposed in this paper: the resonant type, the fastsaturation reactor typewhich are connected to secondary side of CCVTs. Frequency domain analyses, for voltage ratio magnitude, are carried outfor CCVTs to obtain preferable FSC. Furthermore, using surge suppressors such as metal oxide varistors (MOV) toimprove the performance of the FSCs is investigated. Time domain simulations demonstrate that ferroresonance can becleared in few cycles in presence of FSCs. The Electromagnetic Transients Program (EMTP) is used for modeling and finetuningthe FSCs.
