Electrical Earthing
Earthing or grounding It is the process of transferring the immediate discharge of electrical energy directly to the Earth with the help of the low-resistance wire. The electrical earthing is carried out by connecting the non-current-carrying part of the equipment or the neutral part of the supply system to the ground. A safety measure devised to prevent people from getting shocked if the insulation inside electrical devices fails is called Earthing. The third pin in the plug is actually the “Earth” or “Ground” connection of the electrical appliance. The Earth, being a good conductor of electricity, acts as a convenient path for the flow of electrons that escape the insulation. Furthermore, the gigantic size of the Earth paves a path for the safe discharge of the electric charge. Why is Earthing/Grounding necessary? There are 3 mains reasons why all electric devices need to be connected to the Earth. Human Safety - A properly earthed device doesn’t leak out any current. This preve...
