This paper deals with the evaluation of electromagnetic influence of AC traction network on the overhead railway communication lines. The dependence of voltage on a convergence width of communication lines and traction network are given. The experimental research of harmonics in traction current and the theoretical investigation of their influence on communication lines were carried out.

The impact of high-quality installation and grounding of filters for educational purposes is described. The objective is to train students and to show the differences between the theoretical and actual performance.
