Title: Stray current control in DC railway systems
Keywords: current control; leakage currents; railway electrification;

Abstract: DC electrical grid system for railway transport feeding in Bulgaria uses track rails as a return path (feeder) to the substation. When this type of feeding is used the underground utility structures and the transportation equipment are exposed to active corrosion because of the stray currents going from the rails to the earth. This report discusses monitoring methods and the probability for stray current appearance.
