要約(英語): In Japan, including in the Chugoku region, overhead groundwires and surge arresters are used as lightning protection equipment on power distribution lines. Nowadays, surge arresters are installed at regular intervals (200-300m; every 4-6 spans) on distribution lines. Recently, current-limiting arcing horn with zin c oxide elements have additionally been installed on power distribution lines as lightning protection equipment. However, there has been little quantitative evaluation of the effect of installing surge arresters and current-limiting arcing horn with zin c oxide elements on distribution lines on reducing lightning outage and the construction cost. It is very important to evaluate their cost and their effect on reducing lightning outage.In this paper, we show an analytical study of rational lightning protection measures with these equipment for power distribution lines using assessment method of lightning risk. Then we propose rational lightning protection measures in the Chugoku region.
