“…Another example of the standardization and guidance of the lightning protection system was required to efficiently reduce the train operation disruptions due to the shutdown of power supply effected by the lightning strikes in Bogor Station of DAOP 1 Jakarta, Indonesia [6]. The awareness of the design of the lightning protection is important which eventually should ensure that fault or lightning currents would not impact the equipment and passenger in the railway station [7]. From those reasons of several damages, the estimation of touch and step voltages, which is another method to assess the lightning protection, due to lightning impulses and the impacts on the human body in a railway station is paramount.…”

This article proposed a computer-based simulation approach to estimate touch and step voltages due to a lightning strike at a mass rapid transit railway station. A purely resistive circuit model of a station lightning protection, and earthing & bonding system is formed in MATLAB/Simulink with Yaek Nonthaburi 1 passenger station of MRT purple line in Bangkok, Thailand as a case study. The simulation investigated the consequence of a lightning strike at four different locations on the roof of the station and examined whether or not the lightning protection system met the standard requirements. The results showed the touch voltages, step voltages and body currents in a steady state together with the impact on the human body standing in the station. The simulation can guarantee the effectiveness of the proposed model, and also proved that the lightning protection system of the station is able to conform to the standard and there is no harm for the passenger in the station.
