protects
people from injury, structures from damage and elec-
trical equipment from failure due surge voltages. Lightning strikes Germany around two million
times year, and that figure rising. Discharges oc-
cur both rural and densely populated areas, endan-
gering people, buildings and technical equipment.
A lightning protection system consists both external
and internal lightning protection measures.
Key data about lightning:
• 1,500,000,000 lightning strikes annually per year
• 2,000,000 lightning strikes Germany per year
• 450,000 instances surge voltage damage Ger-
many per year
• Surge voltage damage can occur over radius of
up from the location the lightning strike
• The majority lightning strikes are magnitude
between and kA
