Abstract

According to the korea standard (KS)'s definition through 'KSC IEC 61643-1(2007), A SPD(Surge Protective Device) is an appliance designed to protect electrical devices from voltage spikes and the principal components used to reduce or limit high voltages can include one or more of the nonlinear components. 4 type of those nonlinear components are utilized in accordance with korea standard's IEC regulation. The SPD is installed the place(in and out side of installation for protecting damage due to the inflow of light surge) which we need by combination of nonlinear components. In this study, the analysis based on the characteristics of SPD from PF track circuit are discussed.
