Aims to: identify the generic problems involved in lightning protection of wind turbines; collect and systematize existing experience with both older and new designs of wind turbines; describe appropriate methods for evaluating the risk of lightning damage to wind turbines, thereby making reliable cost-benefit evaluations of lightning protection efforts possible; describe and outline appropriate methods for lightning protection of wind turbine components, considering the special nature of wind turbines and the extensive use of composite materials; compile a technical report outlining problems and solutions as seen today.

Identifies the generic problems involved in lightning protection of wind turbines; describes appropriate methods for evaluating the risk of lightning damage to wind turbines; describes and outlines suitable methods for lightning protection of wind turbine components.
