“…The special design of capacitor voltage transformers (CVT) ( Figure 3) makes them particularly prone to the ferroresonance, so they often present a ferroresonant suppression circuit. This circuit should not affect either the transient response or the accuracy of the transformer, only limiting the duration of the ferroresonant oscillations [21,[23][24][25][26][27]. Nowadays, there are mainly two types of ferroresonance suppression circuits in CVTs: Active Ferroresonance Suppression Circuits (AFSC) and Passive Ferroresonance Suppression Circuits (PFSC).…”

Over the last decades, power disturbances have become an important factor on the increase throughout electrical networks, which can exert an important influence over power quality ratios. Amongst them, it is worth mentioning ferroresonance, which is a special case of resonance involving non-linear inductances that mainly affects the functionality of transformers. Its effects are characterized by high sustained overvoltages and overcurrents with maintained levels of current and voltage waveform distortion, producing extremely dangerous consequences. The first step against ferroresonance is always to prevent it from appearing, so it is important to identify those electrical configurations prone to the appearance of the phenomenon. Therefore, this paper analyzes different ferroresonant configurations that may take place in power systems, highlighting some of the most relevant aspects of each configuration.

“…A coupling capacitor voltage transformer (CCVT) is a type of voltage transformer (VT) that is employed to step down measurement voltage in extra high-voltage power systems [1,2]. A CCVT is constructed from four general parts including capacitor units as a divider, a reactor as a compensator, a VT so-called as intermediate VT (IVT) for stepping down the reduced extra highvoltage and ferroresonance suppression circuit (FSC) as a damper.…”
