GI Plate Earthing
GI (Galvanized Iron) plate earthing is a widely used method for grounding electrical systems, especially in areas with high soil resistivity. This technique involves the installation of a flat plate made from galvanized iron, which is embedded in the ground to serve as the grounding electrode. The GI plate provides a substantial surface area that helps in dispersing fault currents effectively into the earth. The galvanization process protects the iron plate from rust and corrosion, thereby enhancing its longevity and reliability.
By establishing a low-resistance path for electrical faults, GI plate earthing helps safeguard both people and equipment from electrical hazards. It is particularly advantageous in situations where traditional rod grounding might not be as effective due to poor soil conductivity. Additionally, the installation of GI plates can be more practical in certain environmental conditions and offers a cost-effective solution for ensuring reliable grounding in various electrical installations.
