| Research Abstract |
Observation of lightning attachment process is necessary for improvement of lightning protection of transmission lines and wind turbines, and for a survey of protective zone of a lightning rod. However, without a high-speed camera, which developed recently, the observation was quite difficult. Because no one knows the time and place of lightning strokes.
A high-speed camera was used for the observation. As of December of 2013, 11 lightning flashes were observed. Most of the lightning flashes were negative downward flashes, which is most important for lightning protection.
