Electric railways are currently developing the technology continues to greener public transport due to logistical capacity enhancement and energy costs savings. Electrification rate of the domestic has also increased significantly. But these electric railway is a situation that needs attention is more extreme cases lead to an accident due to a large tragedy for the purpose of mass transit. Such scrutiny shall be made on the electrical risk factor in operating a railway. A catenary system in the electric railway is an important key technology to determine the speed of the train as a plant for supplying power to the train.
In this paper, the arc generated in the electric railway and analyzed the effects of an electric railway system circuit. In the case of arc extinction in a very short time, but due to the large stand intellect current EMI, thereby causing EMC problems. The impact of this arc can critically affect the entire electrical and control systems continue to accumulate if the railway meeting. By analyzing the effects on the arcs of the catenary system to such high-speed solves the problem of the present system and increase the arc current collecting performance conducted a study in order to take advantage of the construction and performance verification to the new catenary.
