Wind turbines play a vital role in renewable energy generation, but their height, remote locations, and exposure to extreme weather conditions make them highly vulnerable to lightning strikes. Without effective protection, turbines can suffer severe damage, leading to costly repairs and prolonged downtime. A robust lightning protection system is essential to safeguard critical components and ensure long-term operational reliability.

Why Lightning Protection is Essential for Wind Turbines

Every wind turbine design must account for the risk of lightning strikes throughout its operational life. Strikes can cause significant damage, particularly to the main rotor bearing, leading to pitting, abrasion, and a reduced lifespan. In some cases, a single strike can shorten the rotor bearing’s usable life by up to a third.

Repairing or replacing key components, such as the rotor bearing, can be extremely costly, often requiring the removal of the entire rotor assembly. This not only results in financial expense but also leads to downtime, impacting energy generation and overall efficiency.

BGB’s Advanced Lightning Protection Systems

At BGB, we specialise in designing and supplying advanced lightning protection systems tailored specifically for wind turbines. Our solutions are engineered to protect critical components and mitigate the destructive impact of lightning strikes.

One of our core technologies 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 the electrical charge from a strike is safely conducted away from critical components, minimising potential damage.

Compliance with International Standards

BGB’s lightning protection systems are developed to meet the highest industry standards, ensuring exceptional reliability and performance. We comply with:

• EN 61400-24, Table D4 – The industry benchmark for wind turbine lightning protection.
• IEC 62305 – The international standard for protection against lightning-induced surges and generator component safeguarding.

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

Our systems undergo rigorous testing, including high-current simulations at 200kA to replicate real-world lightning impulse currents and long-term charge transfer. This certification confirms their effectiveness in protecting wind turbines from high-energy strikes.
