초록
DC feeding system is mainly floating but the rail potential and the leakage current are created because of long parallelism between rails and ground. Rail potential causes electric shock to human and leakage current causes electrolytic corrosion to nearby the buried metals. Therefore the design technologies to reduce, protect and monitor these effects are important recent DC feeding system. Rail potential and leakage current are analysed based on propagation theory that is utilized in order to simulate grounding system. New measurement procedure is proposed based on this analysis in order to more be accurate in result.
