Strike the lightning away
LM Wind Power’s wind turbine blades are equipped with the new SafeReceptor, Insulated Lightning Protection System (ILPS), which is fully compliant with IEC 61400-24, the latest international standard for lightning protection in blades.
The SafeReceptor has improved insulation efficiency and is much simpler with fewer components and connections. It offers the highest level of lightning protection – Protection Level 1, according to IEC standards. LM Wind Power blades equipped with SafeReceptors provide maximum protection from all natural lightning strikes and ensure that these strikes do not wreak havoc with your Annual Energy Production (AEP).
The SafeReceptor system was assessed by GL for compliance with IEC61400-24 on design parameters and has been approved with a “GL Statement of Compliance”. In addition, the SafeReceptor system has also been awarded a “GL Component Certificate” after a thorough manufacturing evaluation of a blade fitted with the SafeReceptor system. We are the first wind turbine blade manufacturer to receive this certification.
SafeReceptors work on the principle of capturing lightning as opposed to avoiding strikes. Specially designed lightning receptors on the blade capture lightning and transport it in a safe way down the blades conductor system, without creating too much heat which could damage components and laminates. LM Wind Power’s lightning protection systems are thoroughly High Voltage & High Current tested at facilities in the United States, Canada, Germany and Denmark before they are integrated into our wind turbine blades.
Value of effective lightning protection
Effective good lightning protection in blades can protect against the worst effects of lightning on both blades and indirectly on other wind turbine components like nacelle and towers. A lightning strike has the potential to cause serious damage to the blade adversely affecting blade life and Annual Energy Production (AEP). Strikes can cause energy surges of 200 kA with a temperature of 30,000°C, causing an explosive expansion of air within a blade, which in turn can result in severe damage to the blade surface, cracks on edges and molten glue.
