Chapter The external lightning protection system
.g. Here necessary observe the relevant
separation distance (“s”) between earthed roof struc-
tures and metal systems.
All roof structures must protected with air-termina-
tion rods.
If the roof structure has conductive continuation into
the building (e.
This method should therefore only used where the
building already protected with air-termination rods
whose positions were determined using the rolling
sphere grid method.2 Protective angle method
Using the protective angle method only advisable in
simple small buildings and for individual sections of
buildings.1. This distance safely prevents arcing the
lightning current and dangerous spark creation
