Diagram of the lightning protection zones
The following schematic diagrams shows the implementation of the lightning protection
concept for a building with outside lightning protection. Lightning protection zone 0 shown in
the figure is divided into lightning protection zone 0
A
and 0
B
according to the following
definitions.

Lightning protection zones of a building with outside lightning protection
Principle of interfaces between the lighting protection zones
Measures must be taken to reduce the peak current load and the magnetic fields at the
interfaces between the lightning protection zones.
Each zone-penetrating metallic/electrical system must be incorporated into the equipotential
bonding at the zone transition.
Note
Metal systems include channels, structural parts, pipelines (water, gas and heat), etc.
Electrical systems include power and IT cables and wires (e.g. line voltage, bus cable).
