If the roof structure has conductive continuation into
the building (e. Here necessary observe the relevant
separation distance (“s”) between earthed roof struc-
tures and metal systems. The protective angle method
is well suited determining the positions air-termin-

This method should therefore only used where the
building already protected with air-termination rods
whose positions were determined using the rolling

separation distance (s) from the object pro-
tected. This distance safely prevents arcing the
lightning current and dangerous spark creation.TBS
