Stray Currents from a Train in a Light Rail Transit System

Application ID: 120721


Light rail transit (LRT) systems often utilize DC power for train propulsion. In these systems the potential gradients in the rails may induce stray currents, which corrode adjacent metallic structures.

In this example, the Cathodic Protection interface, using Edge Electrode nodes, is used to model the stray currents from a moving train and the resulting corrosion of a nearby pipe. The 3D domain surrounding the railway and the pipe features different soil conductivities. The impact of changed soil conductivities and pipe position is also investigated.
