Impact of Return Traction Current Harmonics on the Value of the Potential of the Rail Ground for theeder is considered. The studies were caused by the need to ensure the electrical safety of the staff and the infrastructure facilities reliability when passing trains of increased weight. In the process of experimental studies of the high potentials causes in rail circuits, data were obtained indica

Dependence of Power Losses in an Overhead Wiring on the Current Waveform Consumed by an Electric Loc for obtaining different quality of electrical energy consumption. Depending on the parameters of the locomotive, it consumes a different form of current, which affects the power loss in the overhead wiring. To research this phenomenon was carried out computer simulation. The results of the research
