Computation of Energy Absorption and Residual Voltage in a Fourth Rail LRT Station Arresters in EMTP-RV: A Comparative Study

Abstract This paper presents a study on the performance of fourth rail direct current (DC) urban transit affected by an indirect lightning strike. The strike was replicated and represented lightning-induced overvoltage means Rusck model, with sum two Heidler functions as its channel base input, perfect conducting ground. aims to determine whether has any influence regard LRT Kelana Jaya line, DC station arrester. simulations were carried out using Electromagnetic Transients Program–Restructured Version (EMTP–RV), which includes comparison results between 3EB4-010 arrester PDTA09 when induced 90 kA (9/200 µs). demonstrated that showed better coordination insulated bracket rail. It allowed lower residual voltage more dynamic response, eventually resulting in gradient pre-breakdown region decreased ratio high region.
