DISTRIBUTION OF THE OVERHEAD LINE CURRENT BETWEEN RAIL AND GROUND DEPENDING ON THE FREQUENCY AND THE DISTANCE FROM THE SUB-STATION

Tests to determine the distribution of the overhead line current between rail and ground depending on the frequency and the distance from the sub-station were made on a double track electrified line with 25 kV, 50 Hz of the Hungarian State Railways (MAV). The earth current factor and rail current factor are a function of the frequency but do not depend on the position of the train. A calculation method permits the determination of these factors in arbitrary conditions. A mathematical method makes it possible to calculate resonance phenomena or networks with different electrical parameters.
