Earthing

Earthing is the connection between the non-current carrying metallic parts of electrical machine, equipment and earth.

Requirement of Earthing :

• It should protect person and equipment from damage due to over voltage.
• It should flow leakage currents to earth during faulty condition of devices.
• Electro-magnetic Distrubance are eliminate by proper Eathing.
• It should stabilizer circuit protection.

Applications :

• All voltage level appliance at domestic & commercial.
• Metallic Equipment body earthing.
• Transmission, Distribution & telecommunication system.
• Power generating station and substation.
• Lighting Arrester earthing.
• Three phase(Transformer) neutral earthing.
• Sensitive electronic equipment.
• At where electrical safety necessary.
