In this study, modelling of Oymapinar transmission line of the West Anatolian Power System region in Turkey is considered. For the modelling, the Matlab-Simulink is used and the ferroresonance phenomena are applied with a switching operation on this modelling. Collected data shows the overvoltage characteristic as a natural result of the ferroresonance event. In this manner, this is the non-stationary data and it can be separated two stationary parts like before and after the switching and Power Spectral Density (PSD) functions are calculated in the logarithmic scale of the amplitudes. Hence, as a result of the ferroresonance phenomena, gain changes in the spectral amplitudes are presented in decibel units. This is given an observable result in the logarithmic spectral domain of the overvoltage effect.
