A Study of AM Broadcasting Antenna's Lightnning and Ground System
AM방송안테나의 낙뢰와 접지에 관한 연구
Abstract
The lightning which is occurred in different regions Contains 80% of whole between June and September. There were the lightning accidents at the peak of mountains. As a result, the antenna tower of AM broadcasting Systems build up clyish plain where has a low earth characteristics resistivity. The following have been observed as a Counter lightning Systems such as high frequency choke, sphere gap(75, 000 V/inch) and reflective power detection relay.
地域的으로 相異하게 發生하는 落雷는 6~9月이 至體의 80%를 차지하였고 山頂에 雷事故가 많았다. AM放送 안테나는 大地固有抵抗이 적은 곳인 粘土의 平野지대에 置局해야 하고 高周波 Choke, Sphere gap(75,000 V/inch) 그리고 反射電力檢出리레이 등을 設置하여 雷事故를 줄일 수 있음을 確認했다.
