RC snubbers are the most common surge suppression solution to minimize the probability of reignition, mitigate high frequency oscillations, and dampen the peak value of TRV and shunt reactor terminal voltage. RC snubbers are equipped with surge arresters to complete the protection. Two surge arrester types, which are Gapped and Non-gapped MOVs, are investigated in this paper. The power system was modelled using PSCAD\/EMTDC software. Considering with\/without RC snubbers, comparisons between two surge arrester types are carried out in terms of the overvoltages. It also presents the energy requirement level of the surge arresters. The simulation results show that Gapped surge arrester overvoltage protection performance is superior to the Non-gapped equivalent arresters.<\/p>\n<style
