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.

The Electrical Behaviour of Railway Pantograph Arcs
Energies, 2023 Electric arcing is an unavoidable consequence of the current collection process by sliding contact in railways and metros, and in general in many electrified transportation systems (ETSs). The most relevant consequences in an electrical perspective are: the occurrence of transients triggering resonant behaviour and transient responses, reduction of the
