在将架空线路提升到更高电压水平时，通常难以实现提升结构所需的间隙水平。使用输电线路避雷器（TLAs）是控制过电压的有效技术，从而实现所需的间隙裕度。本文讨论了这种技术在减小间隙裕度方面的适用性。本文以一条275 kV架空线路改造为400 kV架空线路为例进行了研究。
While uprating an overhead line to a higher voltage level, it is often difficult to achieve the required clearance level for the uprated structure. Use of Transmission Line Arresters (TLAs) is an effective technique in controlling overvoltages and thereby, achieving the required clearance margin. In this paper, suitability of this technique in reducing the clearance margin is discussed. A case study on uprating an existing 275 kV overhead line to 400 kV is investigated here.
