- 초록
- The communication line installed nearby the high-speed train railroad has induced voltage caused by high electric current which is supplied to electric car line. At this point, shielding effect can be expected in communication line, if structure which includes metals is placed around. In this paper, the screening effect was analyzed through experiments when a metallic pipe was buried near the communication line. The result of experiment conducted in high-speed railroad site shows induced voltage decreased to 75% level when a metallic pipe is buried in parallel with near the communication line rather than not the case. This result can be utilized to analyze screening effect by a structure including metal.
