도시철도차량 전선의 수명특성 평가분석

Several kinds of Electrical Wires have been used in Electric Multiple Units(EMU) for the supply of electric power, supervision, and the propagation of control signals. These Electrical Wires must be inspected for safe and stable operation of EMU. The degradation diagnosis and service lifetime to estimate the integrity of Electrical Wires has recently been requested according to the long use of EMU. This paper describes on application of diagnosis method and lifetime estimation EMU. This study is focused on development of diagnosis method and establishment of evaluation standard for urban railway vehicle.
