Ferroresonance is a phenomenon usually initiated by transients in power networks resulting from e.g. switching operations or ground faults. Non linear behavior of the core of an inductive voltage Transformer results in magnetic saturation. In this context, this paper presents the numerical simulation developed with ATP/EMTP software on the ferroresonance phenomenon in inductive voltage transformer to metrological use. The analyzed results arise from the interaction between the applied voltage transformer and the shunt capacitance of the switch. The results show the influence of these variables on the phenomenon of ferroresonance.
