The electric field of the sliding contact during the interaction of the pantograph and the contact wire

Abstract

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 arc creates a strong electromagnetic disturbance that spreads in the surrounding space. This disturbance interferes with communication channels, facility management systems, and telecommunications located in its influence zone. Determining the magnitude of the potential of the electric field at the point of contact will determine the degree of the harmful effect of arcing on adjacent objects and develop a technology to reduce the interfering effect.
