At the present time, the majority of lightning protection methods are abased primarily on the interception and redirection of a lightning strike. Their operating principle is to create an environment in which the lightning strikes into a specially selected and designed lightning rod, after what the lightning current will be directed by down conductors into the ground and distributed in it with the help of the grounding device.
