【 摘 要 】

To solve the metal corrosion problem of transmission line tower grounding grid, a composite grounding material technique based on flexible graphite grounding is proposed. Using CDEGS software, the power frequency grounding resistances with different soils layers and different ground network size of tower are simulated. The researches show that layered soil resistance can be reduced by laying vertical grounding body and uniform soil can reduce ground resistance by increasing grounding network size.
