Lightning protection for wind farms

 

According to a survey by NEDO (New Energy and Industrial Technology Development Organization)*, the biggest source of damage to windmills is from natural causes, accounting for 38% of all damage, with almost all of that accounted for by lightning strikes. The shortest length of time that windmills are put out of action by lightning strikes is 3.5 days, the longest 343 days, and the average 64 days. It is no exaggeration to say that lightning strikes constitute a serious threat to wind farms.
