Novel image-free arc detection method for pantograph–catenary systems based on direct DWT–ANN signal analysis (opens in new tab)

Arc faults in pantograph catenary systems pose a significant threat to the reliability, safety, and efficiency of the electric railways. However, Conventional approaches relying on image processing and deep learning are hindered in real-time applications due to computational delays exceeding the arc time constant. Therefore, this study proposes a novel image-free arc detection method that directly analyzes measured traction current signals using DWT–ANN (Discrete Wavelet Transform-Artificial ...
