The Front Cover

Lightning damage stubbornly remains a major O&M expense for owner-operators in cost and frequency. Damage such as blade skin punctures, shell delamination, split trailing edges, and (less frequently) catastrophic damage to wind turbine blades is costly to repair and causes undesirable downtime. Arctura has developed a wind turbine blade coating that reduces lightning damage to turbine blades by encouraging surface flashovers (see page 7). (cover image: courtesy NTS Lightning Technologies).
