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.

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
