Have you ever received a mild shock when touching certain appliances that are in use? These shocks can be dangerous at times and cause significant problems. This process of sharing charges with the earth is referred to as Earthing. Earthing is a simple method for preventing current leakage and thus protecting devices from electrical damage. Grounding is another safety process that protects the entire power system from failure and is primarily used to unbalance the load when the electric system overloads.
Earthing is used in almost every electrical installation. The conductors are thus regulated about the earth’s conducting surface by the earthing system. The ability of an earthing system to withstand corrosion determines its long-term viability. Because the earth electrodes are in direct contact with the soil or water, they are corrosive.
