Application of GWO-SVM Algorithm in Arc Detection of Pantograph
IEEE Access, 2020 High-speed train will produce pantograph arc during the driving process, which is harmful to pantograph-catenary system. In order to reduce pantograph-catenary system damage, a method based on Gray Wolf algorithm to optimize the binary Support Vector ...

Dynamic analysis using finite elements to calculate the critical wear section of the contact wire in suburban railway overhead conductor rails [PDF]
, 2008 The purpose of this study is to determine the critical wear levels of the contact wire of the catenary on metropolitan lines. The study has focussed on the zones of contact wire where localised wear is produced, normally associated with the appearance of

A heuristic wear model for the contact strip and contact wire in pantograph – Catenary interaction for railway operations under 15 kV 16.67 Hz AC systems [PDF]
, 2020 The sliding contact between the pantograph and catenary allows the correct operation of electric trains. However, this contact induces wear on both the components involved in the process, namely the contact strip on the pantograph and the contact wire on

How pantograph electric arcs affect energy efficiency in DC railway vehicles [PDF]
, 2020 In DC electrified railways pantograph electric arcs represent not only a disturbance, but the step change of the pantograph voltage affects power losses directly and indirectly. The available line voltage is reduced if the train is in traction condition,
