Safeguard wind turbines with BGB's Class 1 Lightning Protection Systems. Reduce damage, cut repair costs, and maximise operational uptime.
Wind turbines are a critical component of renewable energy infrastructure, but their size, location and exposure to harsh weather conditions make them susceptible to lightning strikes. A robust lightning protection system is essential to safeguard wind turbine components and ensure long-term performance and reliability.
The importance
of lightning protection for wind turbines
Every wind turbine design must account for the potential of lightning strikes during its operational life. Lightning can cause significant damage, particularly to the main rotor bearing, leading to pitting, abrasion, and reduced lifespan. In some cases, the rotor bearing's usable life may be reduced by up to a third due to the effects of a strike.
The costs of repairing or replacing critical components such as the rotor bearing are substantial, often requiring the removal of the entire rotor assembly. These repairs not only incur financial costs but also result in downtime that can impact energy generation and operational efficiency.
BGB’s comprehensive lightning protection systems
BGB specialise in designing and providing lightning protection systems tailored for wind turbines. Our products are integral to safeguarding key components and mitigating the detrimental effects of lightning strikes.
One of our key offerings is a lightning protection product that creates a low-impedance path, bridging the interface between the rotating hub bearing and the nacelle. This ensures that electrical currents from a strike are safely conducted, protecting critical components from damage.
Compliance with international standards
BGB’s Lightning Protection Systems are designed to meet the highest industry standards. We comply with:
EN 61400-24, Table D4 – Addressing lightning protection for wind turbines.
IEC 62305 – Providing rigorous tests for safeguarding generator components.
We are proud to have achieved the highest Lightning Protection Level, Class 1, which corresponds to:
Surge current pulses: 10/350µs, 200kA.
Long-duration current: 200C.
These stringent tests demonstrate the reliability and effectiveness of our systems in protecting wind turbines against high-energy lightning strikes. The certifications ensure the resistance of lightning protection systems are verified through a series of high-current tests at 200KA in a fraction of a second to simulate lightning impulse current and long-term current.
