Abstract:  A corrosion of grounding grid might lead to the deterioration of grounding performance. Thus, a damage of power equipment or a threat to people might occur when the power system encounters a short circuit or is struck by lightning. There are many ways to inhibit the corrosion of grounding grid, and the utility of conductive coating is one of the simple and effective ways. This paper summarizes the factors affecting the corrosivity of the soil, describes the conductive property and anticorrosive mechanism of the conductive coatings, and discusses the application prospect of conductive coatings for the corrosion protection of grounding grid.
