Novel image-free arc detection method for pantograph–catenary systems based on direct DWT–ANN signal analysis

Abstract 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 exceedin...
