State and model building regu-
lations require lightning protec-
tion
Earthing systems
If the conducted lightning current reaches the earthing system,
then approximately per cent the energy passed into
the ground, while the other half distributed via the equipoten-
tial bonding system.

foundation earth electrodes
Equipotential bonding systems
These form the interface between external and internal lightning protection. They
ensure that dangerous potential differences not come about the building.

Air-termination and conductor systems
Direct lightning strikes with energy 200,000 are reliably intercep-
ted air-termination devices and conducted into earthing system
through the conductor systems
