Dataset of measured and commented pantograph electric arcs in DC railways [PDF]
Data in Brief, 2020 DC railways are characterized by particularly intense arcing caused by pantograph detachment, due to the large current intensity and the general implementation of onboard resonant filters, whose transient response is triggered by electric transients ...

A Novel Method for Calculating the Radiated Disturbance From Pantograph Arcing in High-Speed Railway [PDF]
IEEE Transactions on Vehicular Technology, 2017 Pantograph arcing is a key electromagnetic disturbance source to affect train control system in high-speed railway. Since the characteristics of pantograph arcing is related to train speed, it is necessary to investigate effective numerical modeling and ...

Pantograph-To-OHL Arc: Conducted Effects in DC Railway Supply System [PDF]
IEEE Transactions on Instrumentation and Measurement, 2018 The electrical arc occurring in the sliding contact between the supply contact line and the current collector (pantograph) of an electrical locomotive is a fast transient phenomenon able to degrade progressively the line-To-pantograph contact quality and,

Study on the Ablation of Slide Plate by Pantograph–Catenary Arc Based on Pantograph Slide Material
InfrastructuresThe ablation of pantograph sliders caused by pantograph–catenary arcing is a critical issue in the operation of pantograph–catenary systems. The arc discharge induces localized high temperatures that lead to the melting and even evaporation of the slider

Pantograph Arc’s Energy Characters Under Various Load
机车电传动, 2011 Due to the increasing speed of the locomotive, the pantograph-catenary disconnection was getting worse, and the pantograph arc occured frequently. The pantograph arc etched the pantograph slider and contact wire, and the etching level was influenced by ...
