초록

본 논문은 낙뢰에 의해 전송 선로에 유기되는 유도뢰 전압을 해석하고 낙뢰 위치 및 선로 길이에 따른 유도뢰 전압의 크기, 파두장, 파미장 등에 대한 낙뢰 파라미터 변화를 분석하였다. 분석한 결과를 확인하기 위해 실제 통신 선로를 대상으로 유도뢰 전압을 측정하였다. 선로 길이가 길어짐에 따라 그리고 낙뢰 위치가 선로와 멀어짐에 따라 파두장, 파미장이 증가하는 경향을 확인하였다. 전체 선로 길이보다는 가공 선로 길이가 상대적으로 유도 전압 크기에 영향을 끼침을 확인하였다.

In this paper, the Induced voltage on transmission line by lightning was calculated using FDTD method and the lightning parameters such as peak voltage, rise time, and decay time for the lightning location and line length were analyzed. To verify the results, lightning induced voltage was measured in the field using real telecommunication line. Results from the collected data were compared with the calculated results. It was found that the rise time and the decay time were increased as the line length and the distance between the line and lightning location were increased. Also, the peak voltage was affected more by the overhead line length than by the total line length, while the rise time and the decay time were more affected by the total line length.
