Abstract:
Corrosion of the grounding grid is the most defective parameter, which has affected on the grounding grid performance and its ability to ensure its main target of stability and safety of the electrical systems. In order to indicate the corrosion degree (η) of the grounding grid and its effect on the grid current distribution plus the grounding grid lifetime, mathematical model has been investigated. It has been applied on different shapes of steel grounding grids buried in two layers soil. Moreover, experimental study has been carried out to investigate the relationship between the corrosion degree (η) and the contact resistance (Rcont) of the galvanized steel grounding grid with different shapes at low resistivity conditions.
