In late years, with the rapid spread of wind turbine generator, the damage by lightning becomes a serious problem. Additionally, recent wind turbine generator grows larger, so that it becomes a cause to let the lightning damage increase. Because cost and time for repair, transportation and exchange for wind turbine blades is large in comparison with the other parts, lightning protection measures of blades are important. Many studies are already carried out about lightning protection performance of wind turbine blades, and some effective lightning protection measures are suggested. However, it does not yet become clear about a lightning protection characteristic of wind turbine blades. In this report, high voltage impulse tests to the sample parts of wind turbine blade are carried out and are aimed at evaluating lightning protection performance.
