Electric Arc of Pantograph and Catenary

2019
Electric arc is a gas discharge phenomenon, the instantaneous spark generated by current passing through some insulating medium (such as air). The arc is a self-sustained discharge phenomenon.

Ablation Characteristics of Contact Wires in the Pantograph–Catenary System under Successive Arcing Events

2025 IEEE China International Youth Conference on Electrical Engineering (CIYCEE)
Offline arc is a characteristic phenomenon in the dynamic interaction of the pantograph–catenary (PC) system, and its repeated occurrence leads to pronounced ablation of the contact wire surface.

Direction Finding Technique Based on Poynting Vector Magnitude for Pantograph Arcing

International Conference on Embedded and Multimedia Computing, 2019
Pantograph arcing can create many types of prob- lems to railways, inclusing EMC issues. In the present work we propose a direction finding technique aiming at the localization of the arcing event with low computational load.

A novel method for detecting the pantograph–catenary arc based on the arc sound characteristics

Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2018
In recent years, the speed and the current transmission density of high-speed railways are increased. As a result, the rate of the occurrence of pantograph–catenary arc also increases, which directly influences the service performance of the pantograph–catenary system.

DBA-Net: Dual-Bilinear Attention Network for High-Speed Railway Pantograph Arcing Detection

2026 3rd International Conference on Electrical Technology and Automation Engineering (ETAE)
Pantograph-catenary arcing is a critical fault phenomenon in high-speed railway systems, posing severe threats to the stable current collection and the service life of equipment. Detecting arcing accurately is challenging due to the small size of the arc,

A novel real-time arcing detection model of pantograph-catenary for high-speed train

IEEE International Conference on Electro/Information Technology
The arcing happened in Pantograph-catenary system could damage railway operation. Arcing are characterized by short and volatile durations, making it challenging to rapidly detect and segment arcing of varying shapes and sizes. To address these issues, a
