The Lightning Interception Blade Implant (LIBI®) is a new standard of lightning protection for wind turbine blades.
The LIBI solution is suitable for both new blades and for improving existing blades by retrofit.
By ensuring that lightning strikes are captured with high efficiency and safely directed down through the wind turbine blades, LIBI® offers complete protection from damages and downtime due to direct strikes to wind turbine blades.
Lightning-related damages are a major concern to the wind power industry and one of the main reasons for longer outages. Depending on location, topography, weather conditions, and wind turbine height, lightning can strike a wind turbine more than 25 times a year. This problem is growing in line with the height of wind turbines.
The taller the wind turbine, the higher the risk of direct lightning strikes. The tendency of moving wind turbines even further offshore, simply results in increased maintenance and repair costs.
Due to such extended lightning exposures, the operation and maintenance costs increase while the Annual Energy Production decrease, resulting in a higher Cost of Energy (CoE) than expected. Enhancing the performance of wind turbine lightning protection systems will help alleviate this problem.
LIBI® provides a cost-effective solution to lightning protection of the outermost 5m of a blade. This ensures high interception effectiveness when exposed to direct lightning strikes. The innovative blade concept has been designed using state-of-the-art technology and tested in excess of 200 kA using the GLPS testing facilities, guaranteeing that it can withstand the expected high impact from lightning strikes.
Furthermore, our concept adaptation process ensures quick and effective adaptation to the geometry of every specific blade design.
The LIBI® concept gives you the following unique advantages
