Analysis on Voltage Rise of Rail in High speed Railway System

고속철도 시스템의 레일 전위 상승 해석

In electric railway system, potential of rail has been risen, for return-current flows through rail. The magnitude of rising voltage is different to railway feed system, ground admittance of rail and the load current. If rising voltage of rail is large, electric shock can be occurred to passengers and maintenance-worker. In this paper, we estimate the rising voltage of rail in high speed railway system and check the safety to human beings.
