Observation of upward lightning hitting Tokyo Skytree by using high-speed camera

对雷电附着过程的观察是提高输电线路和风力发电机组防雷工作的必要条件，也是进行避雷针防护区域调查的必要条件。但是，如果没有最近开发出来的高速摄像机，观察起来相当困难。因为没有人知道雷击发生的时间和地点。使用高速摄像机进行观察。截至2013年12月，共观测到11次闪电。大多数闪电为负向下闪电，这对防雷至关重要。

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.
