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.
