Chapter The external lightning protection system
.1 Air-termination systems
Air termination systems are the part the lightning
protection system that protect the building structure
from direct lightning strikes.
2. The external lightning protection
system
The external lightning protection system consists of
air-termination systems, down-conductors and the
earthing system. With these components able to
perform the functions required it, namely intercept-
ing direct lightning strikes, discharging the lightning
current earth and distributing the ground.TBS
