Evaluation of Electromagnetic Compatibility of Electric City Transport with the Automatics Systems

This paper deals with the evaluation on electromagnetic compatibility of city rail transport systems 750 V dc in Ukraine, Indonesia, Malaysia. The results of simulation of electromotive forces at the different frequencies are given. The experimental research of signal current and electromagnetic interferences in the track circuits is shown presence of 300 Hz harmonics near station and 275 Hz on some railway sections, which could be stop movement of trains.
