An Active Lightning Protection (ALP) System combines protection with lightning detec-
tion.
Functionality
• Carrying out preventive measures in advance
• Triggering an early streamer of ionised air.
The streamer intercepts lightning discharges for the safe passage to a low
impedance down-conductor.
