Abstract:	避雷器被廣泛應用於電力系統之雷突波防護，主要應用包括輸電系統及變電所電纜連接站、變電所及配電架空系統之變壓器之保護，本文主要探討一般電力設備與電纜接續處裝設避雷器相關計算，包括設備最大保護距離計算、電纜保護臨界長度計算及避雷器接地引線長度對保護裕度影響，文中同時探討避雷器接地引線選用耐流計算。 Arresters are widely used for lightning protection. Arresters are installed at the cable connection stations of substations and on transmission towers, the transformers of substations and on distribution overhead systems. This paper investigates the effects of arrester separation distance on both protected pieces of equipment and underground cables. The protective effects of arrester grounding lead length on protective margin and the current rating of arrester grounding lead are also studied.
