Electromagnetic Influence of AC Traction Network on the Railway Communication Lines

“…Measurement apparatuses were connected before filters at the appearance of interferences and noise in the channel of communication during control and regulation of it. Maximum allowable peak interference values of the electromagnetic fields arising from the rollingstock at the movement are given for the AC, DC, diesel traction power systems in [11], [12]. These dependences are linear and they reduce from 70 to 20 dB at the 0.15…30 MHz and from 90 to 65 dB at the 30…1000 MHz with the AC power traction system [13].…”
