What is Earthing? What is the Necessity of Earthing? How many types of Earthing used in Industry? Electrostatic charges? Lighting Arrestor? Safety of Electrical Machines? Continuity and Insulation?

Question

Accepted Answer

Earthing is the process of connecting the metallic parts of an electrical appliance or installation to the earth plate.

Earthing is necessary to protect people and equipment from electric shock and to ensure proper functioning of electrical systems.
There are several types of earthing used in industry, including plate earthing, pipe earthing, and rod earthing.
Electrostatic charges can build up on objects and cause damage or injury, so grounding is important to dissipate these charges.
Lightning arrestors are used to protect buildings and equipment from lightning strikes by providing a path for the electrical current to follow.
Safety of electrical machines can be ensured through proper earthing, insulation, and maintenance.
Continuity and insulation are important aspects of electrical safety, as they help prevent electrical faults and ensure proper functioning of equipment.
