Lightning damage of blades is the most serious problem in wind turbine generators. The mechanism and cause of such damage are investigated by lightning observation and high-voltage and large-current experiments. Lightning damage of the blade of a wind turbine still remains a problem even if receptors and a down conductor are installed. A new development for better protection measures of blades, including not only a better form and layout of receptors but also independent lightning towers and new materials for blades, is necessary.
