Abstract :
DC electrified traction systems are a potential source of stray current, that may corrode both internal and external structures and installations. The stray current intensity depends on several factors (traction current, rail insulation, concrete mat and piers resistance), that are accounted for in the proposed model. Moreover, the effect of a uniform or multi-layer soil model is considered, showing the differences and the impact on the countermeasures with respect to a uniform soil model simplifying approach.
