The air-termination systems form protective
spaces, the necessary size which can determ-
ined using, for example, the “rolling sphere method”. For lightning
currents, this creates conductive path into the
ground. case direct
strike, the lightning protection system protects the
building against fire. The equipotential bonding system creates
the connection into the building.
Alongside the air-termination system and the conduct-
ors, the earthing system another integral part the
external lightning protection system. The lightning cur-
rent needs safely routed into the earthing sys-
tem without any sparking arcing into other metallic
structures.
