N2 - Inductive Voltage Transformer (IVT) is one of the critical elements in the electrical system that cannot be separated from the potential for ferroresonance due to the inductive and capacitive nature in it. In this study, the effects of the ferroresonance phenomenon on IVT caused by switching. This phenomenon can cause overvoltage in IVT. The simulation of ferroresonance was done with software ATPDraw/EMTP. The variables studied include variations in grading capacitance (Cg) and shunt (Cs), as well as the switching time with a time span of 0.02 seconds. The simulation results showed that the variation of grading capacitance (Cg) obtained peak voltage reaches 180.74% of the normal peak voltage at a Cs value of 0.01 μF. In the variation of shunt capacitance (Cs) obtained a peak voltage of 764.42% at a Cg value of 0.005 μF while the switching time variation obtained peak voltage of 159.9% in the time span of 0.05 seconds to 0.06 seconds at Cg and Cs values respectively of 0.005 μF and 0.01 μF. According to the results, the value of Cs, Cg, and switching time affect the significance of overvoltage that occurs in IVT as an impact of the ferroresonance phenomenon.
