| Abstract: | An upgrade of a grounding grid of 220kV transmission line tower with 12 bases in Jiulong County, Garze Tibetan Autonomous Prefecture, Sichuan Province is taken as an example of case in this article to illustrate that in the construction work of a grounding grid with high earth resistivity in the surrounding area, the grounding resistance, earth potential and contact voltage of transmission line towers can be effectively lowered by means of multiple layers construction of resistance reducing material and applying an additional restraining ring to the end of the level ground conductors at the base, for the reference of the design of a transmission line tower＇s grounding project. |
