Novel Vision-Based Abnormal Behavior Localization of Pantograph-Catenary for High-Speed Trains

IEEE Access, 2019
To ensure the safe operation of high-speed trains, catenary anomaly detection and alerting security have become an urgent problem to solve. In this paper, we propose a novel method for abnormal behavior localization of a pantograph-catenary for high ...

Study on Pantograph–Rigid Catenary Separation Through Simulation Experiments and the Dynamic Characteristics of DC Arcs

Machines
The pantograph–catenary system is a critical component of the traction power supply network. Due to hard points on the overhead contact line and vibrations of the pantograph, pantograph–catenary separation may occur, leading to offline DC arc events.
