Correctly maintained separation distance (s) between down-conductor systems and roof structures
2.
The separation distance (s) does not prevent induct-
ively coupled surge voltages!
Components with direct connection lightning pro-
tection system
A separation distance does not have observed
in buildings with cross-connected, reinforced walls
and roofs with cross-connected metal facades and
metal roofs. This distance described the separation
distance (s).
What the separation distance?
If there adequate distance between the conduct-
or passing from the lightning current and the metallic
building parts, the risk sparking practically non-
existent.1.

Chapter The external lightning protection system
. Metallic components with conductive
lead into the building protected, and whose dis-
tance the conductor the external lightning protec-
tion system less than one metre, must connec-
ted directly the lightning protection system. This
measure required avoid dangerous sparking
between both air-termination system and down-con-
ductor and also the metallic building parts and elec-
trical equipment.5 Separation distance (s)
All metallic parts building and electrically
powered equipment and their supply cables must be
integrated into the lightning protection system. These
include, although are not limited to, metallic railings,
doors, pipes (with non-flammable and/or explosive
content), facade elements, etc
