Abstract

Palembang Light Rail Transit structure is higher than surrounding object, so it is definitely an easy target for lightning strike. So far, the early streamer emission air terminals only protect stations and important objects in viaduct such as signal and telecommunication poles, and most of the track will be an easy target for lightning strike. If it is hit by a direct strike, there will be very high voltage elevation because the grounding is installed on every 5 piers, in fact it can even reach 12 MV. Installation of grounding on each pier will lower the voltage elevation by 57%. Besides the threat of direct strikes, the voltage can arise from BTS tower and 70 kV transmission wire induction when that objects are struck by lightning. To overcome the threat due to direct strikes and induction, we can install Overhead Ground Wire above the track. Foundation grounding systems significantly reduce the grounding resistance, thus it is the best choice for structure like Palembang Light Rail Transit.
