Safety Analysis for Passengers of Composite Car-body against Lightning Strikes
복합차체의 낙뢰에 대한 인체 안전성 분석

Abstract
In this paper, the safety for passengers of composite car-body against lightning strikes was analyzed by the application of an impulse generator which can produce impulse current up to 50 [kA] with 8/20 [us] waveform. Potential difference on inside surface of the car-body was measured as a safety parameter for the passengers against lightning strikes. The potential difference between 20 [cm] distant was 175 [V] at 37.67 [kA], and it corresponded to 875 [V] between 1 [m] distant. The amount of charge flowing a passenger at 100 [kA] impulse current can be estimated to 0.31 [mA s]. This is much less than the limit amount of charge for human body, 30 [mA s] which is presented by Koeppen and Osypka.
