Earthing or grounding is connecting a body directly to earth. Grounding prevents build-up of electrical stress (high voltages for lighting or cable insulation breakdown), static energy or for use a one of the conductors in power transmission.

At Power Technics Ltd, in partnership with FURSE we offer solutions for protection of structures against lighting with the principles components being:

Air termination network	-	Point of connection for a lightning strike
Down conductors	-	Means of carrying the current of a lightning strike safely to the earth termination network.
Earth termination network	-	The means of dissipating the current to the general mass of earth.
Bonding	-	To prevent side flashing and provide path for earth leakage.
