Individual sparegaps (VLD) substitution by an earthing conductor at railway station

Abstract

The paper deals with the analyses of voltageses on the bare earthing conductor connecting the masts and ports of the overhead contact line at the railway station. Introduction of this earthing contactor can exclude the individual spargaps connecting the mast or port with the rail. The simulation results are recapitulated in diagrams useful for chosen input circuit values and for chosen faulty current 1000 A. The method of the diagrams utilisation is described in the final part of the paper.
