The air-termination systems
provide optimal impact point and are connected to
the earthing system via the conductors. For lightning
currents, this creates conductive path into the
ground.
Alongside the air-termination system and the conduct-
ors, the earthing system another integral part the
external lightning protection system. case direct
strike, the lightning protection system protects the
building against fire. The lightning cur-
rent needs safely routed into the earthing sys-
tem without any sparking arcing into other metallic
structures.

by the lightning protection system. The air-termination systems form protective
spaces, the necessary size which can determ-
