Formation of Interference from Power Circuits to Apparatus of Automation and Remote Control

Some results of research of processes of incipience and formation of the interference on the equipment of railway automatics and remote control. It is shown that the primary source of interference is the appearance of the asymmetry of the resistance in rail lines. It is found that the absolute value of asymmetry traction current in the points connection to the rails of the equipment of rail circuits and in the rails under the receiving coils of the automatic locomotive signaling are functions of temperature of rails, size and harmonic composition of traction current in them, and also sizes of mutual inductances of rail threads with other electric lines.
