The average lightning discharge releases 55 kWh in only 100 to 300 microseconds. This calls for effective methods of protecting blades on wind turbines along with their internal electrical and electronic systems. Most wind turbines work in harsh locations, making them susceptible to damage from volatile weather. Lightning damage, particularly to wind turbines, is often…
Guiding 200,000 Amps Safely to Ground
A main lightning discharge is characterized by rapidly rising current that peaks at about 200,000 Amps and averagesĀ about 30,000 Amps over its duration. Even though the event is over in milliseconds, there is great potential for harmĀ to personnel and damage to equipment. Personnel working around such a hazard that often strikes wind turbines…
