EARTHING

EARTHING

The process of transferring the immediate discharge of the electrical energy directly to the earth by the help of the low resistance wire is known as the electrical earthing. The electrical earthing is done by connecting the non-current carrying part of the equipment or neutral of supply system to the ground

Why Earthing is Required?

The main intention of electrical earthing is to keep away from the danger of electric shock due to the outflow of current .

• Plate earthing
• Pipe earthing
• Rod earthing

The earthing is essential because of the following reasons

• The earthing protects the personnel from the short circuit current.
• The earthing provides the easiest path to the flow of short circuit current even after the failure of the insulation.
• The earthing protects the apparatus and personnel from the high voltage surges and lightning discharge.
