Power conversion by means of semiconductor elements, i. e. the use of thyristors in traction systems operating with dc or ac has resulted in new electromagnetic compatibility problems. While it has hitherto been possible to control the interference to telecommunication installations caused by the fundamental frequency and harmonics of the traction current without great difficulties, the growing number of harmonics may call for special measures to be taken. In addition, traction currents are also increasing due to the demand for higher acceleration and speed of trains, particularly of rapid transit systems in densely populated areas - a demand which can particularly be met by the thyristor technique. This paper examines the electromagnetic compatibility problem from both the viewpoint of the Railways and the telecommunication authorities. Moreover, measures for keeping the interference within tolerable limits are indicated.
