Lightning Protection

 

the complex of measures and technical equipment for protecting buildings, structures, and the equipment of electrical installations from damage by direct strikes of lightning.

Lightning protection is effected by grounded rod-shaped or cable-type lightning arresters, which are erected over the object to be protected. In order to provide dependable protection against lightning, all metal structures and pipes in a building are joined together and grounded. The equipment of electric power-distributing facilities is protected from surges caused by lightning strikes to transmission lines by bus-mounted valve arresters and by the transmission line at the approach to the electric substation.
