Urban Railway was used importantly with transport for several decades. This transportation facilities used electricity. When the breakdown occurs, social, the economic loss is enormous. In addition to, the power equipment was ageing. We need preventive diagnostic monitoring system in order to prevent breakdown of power equipment. In this paper, we investigates characteristic and breakdown type of the Urban Railway power equipment. Through the this research, we can contribute in the operation which power equipment is efficient of the Urban Railway.

Electric Power cable is the apparatus that receives electric power from the Korea Electric Power Corporation and supplies electric power to electric train and annex facilities of each railway station. With substantial ripple effect during power blackout accidents, such power blackout accidents must be coped with by discriminating the status of insulation deterioration of electric power cable in advance. Discrimination of insulation deterioration of the electric power cable is normally executed while the power is disconnected and it is very difficult to discover, at early stage, the insulation deterioration of the power cable in operational state since the duration of inspection is limited. This research aims to consider method of diagnosing the insulation deterioration of electric power cable in On-Line state rather than diagnosis in Off-Line state in order to secure reliability of power supply by reducing duration of power blackout (accidental blackout and blackout during works) and by seeking reduction in equipment and manpower used in diagnosis of deterioration through prevention of the accident itself prior to occurrence through early restoration of accident due to insulation deterioration of the electric power cable and assessment of performance of the cable under operation.

수십년 간 주요 운송 수단의 한가지로 사용되고 있는 도시철도는, 사고 발생 시 큰 경제적 손실과 사회적 손실을 야기할 수 있으나, 사고의 주 원인 중 한 가지인 도시철도 전력설비 고장에 대한 감시 및 진단 시스템은 적용되고 있지 않은 실정이다. 최근 이러한 전력설비 상태 감시 및 진단에 대한 필요성이 점차 커지게 되어, 도시철도 전력설비 수명예측 시스템 설계에 관한 연구 과제가 제안되어 현재 국토해양부와 건설기술평가원, 그리고 한국철도기술연구원의 주도 하에 수행되고 있다. 본문에서는 수명예측 시스템 설계에 필요한 도시철도 전력 시스템의 특성과 고장 사례를 조사하였으며, 각 도시철도 운영기관의 사용자 요구사항 설문 결과, 그리고 수명예측 시스템의 일부인 전력설비 감시진단 시스템 기초 설계 결과를 나타내었다.

Electrical facilities for metropolitan rapid transit is a important facilities for supply power to metropolitan rapid transit, and can cause enormous economic loss and social problem if fault occurs. Because of various social accident, interesting and necessity of preventive disaster diagnosis system increased gradually and we became carrying out a research project for a design of condition monitoring system for electrical facilities of metropolitan rapid transit finally. In this paper, system construction and design result of condition monitoring system for mold transformer which accomplished through research project are presented
