| Outline of Final Research Achievements |
Recently, eco-friendly renewable energy has been attracting attention, the amount of introduction of wind turbines has been increasing year by year. Lightning is one of threats for wind turbines around the coast of Japan, many wind turbines have been damaged by large energy lightning.
In this research, lightning attachment has been clarified using several kinds of measuring systems. The influence of the lightning current shunted to wires incoming or connected to the wind turbine on the lightning damages of electrical and electronics equipment has also verified. Finally, it has been found that there is correlation between coulomb of lightning current and the probability of lightning damage occurrence.
