Eliminate Corrosion on Grounding System By A Conductive RTV Silicone Coating

Corrosion on grounding rod can significantly increase the grounding resistance and compromise the safety of the power system. Silicone rubber used in outdoor insulation area for its long life in adverse environments. This paper proposes a kind of conductive RTV silicone coating suitable for grounding systems. Conductive nano-particles such as carbon black and carbon fiber are added to reduce the resistivity to about 10 Omegaldrcm. Experiment results shows that this material is effective in eliminating corrosion.
