Undervoltage compensation of pantograph catenary arc [PDF]
AIP Advances, 2020 This paper describes the design of a new type of pantograph-catenary arc simulation test device and simulation of the arc generated by the pantograph during operation under laboratory conditions. The influence of the burning position of the pantograph-catenary arc on the overvoltage of the traction system is studied.

Application of GWO-SVM Algorithm in Arc Detection of Pantograph [PDF]
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 Machine classifier to identify pantograph arc is proposed.
