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.

The electric field of the sliding contact during the interaction of the pantograph and the contact wire [PDF]
E3S Web of Conferences, 2021 The process of transferring electrical energy from the contact wire to the pantograph takes place in a dynamic mode. Large currents are transmitted, and even the slightest separation of the sliding contact causes an arc formation.
