Development of a Model of Current Distribution in the Overhead Contact Lines for an Innovative de-Icing System

Icing on the overhead contact line exclude the possibility of efficient current collection from the overhead contact line. The effects oficing can result in losses for carriers due to delay or cancellation of trains and also cases of damage to the traction infrastructure and pantographs. Th e existing methods of de-icing the traction network (mechanical, chemical and electrical) are currently ineffective. Therefore, it is necessary to develop a new electrical method that takes into account the detailed current flow in the overhead contact line. This article presents a model for calculating the current flow in the overhead contact line and the resistances of droppers, suspension elements, and distance holders measured on the basis of actual measurements.
