Lightning Protection System Analysis on Palembang Light Rail Transit Station

摘要

Light Rail Transit (LRT) is a future public transportation that is being developed in Indonesia, especially in Jakarta and Palembang. In Palembang, this public transportation has 13 stations built quite high. The height of the stations can reach 25 to 30 meters. This high-rise buildings will be an easy target for lightning strikes in the area such as Palembang. This is because Palembang is located in the area where the Monsoon wind reversal occurs. This Monsoon wind reversal affects the density of lightning strikes especially in tropical country surrounded by the sea such as Indonesia. The impact of damage caused by lightning strike is enormous. Analysis of lightning protection systems to be applied on LRT stations in Indonesia, especially in Palembang area, is carried out to evaluate the existing protection system. This research analyzes and discusses grounding, bonding, shielding, surge protection for internal protection system and the new innovative Extended Mast Terminal (EMT) for external protection system. This research will provide conclusion for lightning protection system that is suitable to be applied in Indonesia.
