Abstract
Currently, there is a classical idea of current distribution in the rail circuits of 25 kV AC traction networks. However, due to particular complexity of mathematical representation processes occurring in boundary conditions and a variety of interrelated factors, simplified models of traction current flow in rails are considered. In this case, the traction current is considered as induced by contact network—ground circuit. And the role of traction current flowing from train (galvanic traction current) is practically not considered, due to its rapid exit from rail into the ground. However, these methods of representing the path of reverse traction current, as well as the studies and measurements carried out, show a very significant influence of galvanic current in rails on process of forming high rail–ground potentials. The purpose of this study is to analyze causes of the increased rail–ground potential, as well as generalize and describe influencing factors. Understanding these processes will make it possible to develop the most effective technical and organizational measures leading to a decrease in these potentials, and, as a result, an increase in reliability of AC traction power supply system. This article compares the results of mathematical calculations, simulation modeling and direct measurement of interest processes. The problem of increased rail-ground potentials is relevant for the network of electrified railways, on the territory of which heavy and intense traffic is carried out. From the results of earlier measurements, it was revealed that values of rail-ground potentials can reach significant values exceeding 1000 V, and be dangerous both for technical means of accompanying infrastructure and lead to electrical injuries. For these reasons, much attention has been paid to conditions for appearance of high rail-ground potentials.
