TELECOMMUNICATION SYSTEMS IN RELATION TO 50 HZ A.C. ELECTRIC TRACTION

Current methods for reducing the effects of inductive interference in lineside telecommunication cables on railroads, electrified at industrial frequency, are summarized. The methods employed by British Railways for calculating induced longtudinal voltages in cables are outlined, together with standard calculated values in tabular form. The degree of electromagnetic shielding which can be obtained by the use of high-conductivity cable sheaths and steel-tape armoring is illustrated. The effects of the method of traction-current control in motive-power units, with respect to the generation of noise in cables, are discussed.
