To connect the metallic conductive Parts of an Electric appliance or installations to the earth ground is called Earthing or Grounding.

Skip to content. Skip to navigation. Earthing and short-circuiting devices are portable equipment for temporary earthing or earthing and short-circuiting of disconnected or isolated switchgear installations. The aim of earthing and short-circuiting of disconnected or isolated parts in electrical installations is to prevent voltages and electric arcs in the event of an accidental re-closure or when currents are coupled into the system by adjacent energised installations.

Electrical Earthing – Methods and Types of Earthing & Grounding

Definition: 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. Mostly, the galvanised iron is used for the earthing. The earthing provides the simple path to the leakage current. The shortcircuit current of the equipment passes to the earth which has zero potential. Thus, protects the system and equipment from damage.

Electrical Safety - Earthing

If you are having an alteration of addition made to your electrical installation, your electrician must check as well as other things that the earthing and bonding arrangements you have are up to the required standard. This is because the safety of any new work you have done however small will depend on the earthing and bonding arrangements. If there is a fault in your electrical installation you could get an electric shock if you touch a live metal part.

When all metallic parts in electrical equipment are grounded then if the insulation inside the equipment fails there are no dangerous voltages present in the equipment case. If the live wire touches the grounded case then the circuit is effectively shorted and fuse will immediately blow.

The process of transferring an unintended electrical energy directly to the earth through a low resistance wire is called electrical earthing. It refers to the connection of a noncurrent-carrying part of the equipment or neutral of supply system to the ground, which represents the zero potential. The leakage current chooses the simple low resistance path to flow. Thus, the electrical system and equipment are protected from damage. The electrical equipment has two non-current carrying parts such as neutral of the system and frame of the equipment. Earthing system is also classified into two types. The process of connecting neutral of the system to the earth through a GI wire is known as Neutral earthing or System earthing.
