Failure analysis of overhead line and structure at 25 kV using online condition monitoring system in electric railway

초록

Developing a condition diagnosis system that assesses structural health and analyzes failure by monitoring the current condition of overhead lines and structures is currently a very competitive field. According to the needs of electric railways, condition-based monitoring systems have constantly been improved to increase equipment functionality and evaluate failure analysis.Our basic proposal is to achieve continuous online condition monitoring through remote data access, and to easily acquire data from all sensors in order to analyze failure such as arc behavior between a pantograph and an overhead contact line and electrical and mechanical fatigue of a catenary system. We propose a FPGA-based real-time measurement system to monitor dynamic and electrical properties of catenary systems in electric railways.
