Lightning and surge voltages endanger people and
assets.
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
