An Earthing System is a safety mechanism used in electrical installations to prevent electric shock and equipment damage. It connects the electrical system to the ground, allowing excess electricity to safely dissipate into the earth. This is crucial for protecting both people and devices from electrical faults. There are different types of earthing systems, such as TT, TN, and IT, each designed for specific applications and safety requirements. Proper earthing ensures that in the event of a fault, the electrical current has a safe path to the ground, minimizing the risk of accidents and enhancing overall electrical safety.
