Abstract
This paper analyzed the induced voltages on a telecommunication line due to high-speed a.c. electrified railway system. The induced voltages were measured by domestic regulation, 2 test lines with 2 km length were installed near railway in parallel to compare the influence for distance from disturbing line. The analysis was made on the induced voltages with the distance from railway, line length, and the different earthing point, and also on the waveform and spectrum distributions. The statistical induced voltages for the time for a day and dates was analyzed.
