Abstract
This paper presents a low-maintenance system of grounding overhead catenary supports by using reinforced concrete supports and foundations as natural grounding electrodes. An algorithm is elaborated for choosing the optimal length of a group-grounding cable. This algorithm takes into account the system resistance, electromagnetic influences, permissible density of the current flowing from the overhead catenary support hardware, and electrical safety conditions. A simulation model is created that allows monitoring and analyzing electrical safety conditions when running the grounding system with overhead catenary supports as natural grounding electrodes. The correctness of the model’s performance is confirmed by experimentation.
