Earthing Basic Concepts, Types of Earthing, Earthing Pits Construction,
Earthing or Grounding: Earthing, or 'grounding' an electrical network is an essential safety feature, which can protect equipment from electrical faults and save lives. When live wires touch a grounded metallic section, the brunt of the high voltages is safely directed towards the ground. Purpose of Earthing Electrical networks are earthed for three main purposes: 1. As a safety feature for property, equipment and life - An earthed circuit reduces the risk of death or injury by providing an alternate path for current to discharge into the ground. Equipment, appliances and property are protected against faults , leaks and fires resulting from short-circuits and sparking. 2. Protection against over-voltage - Earthing also provides protection against power surges, accidental connection with high-voltage lines and even lightning strikes, allowing the energy to flow to the ground, with minimal effect. 3.
