Wind energy is one of the most mature and scalable renewable clean energy sources available today. Inside wind turbine generators, there are numerous sensitive electronic components, which are very expensive. It’s common to see wind turbine blades damaged or even bent or broken due to lightning strikes every year.

Due to the random nature of lightning, it cannot be avoided. Therefore, installing surge protection devices (SPDs) on the power lines inside the turbine is an essential lightning protection measure. It can quickly dissipate lightning currents to the ground when the wind turbine is struck by lightning, reliably reducing overvoltages to the withstand voltage value of the protected equipment.

Wind power surge protectors are suitable for:

Inverters, wind turbine electronic side, wind turbine rotor side.

Suitable for IT, TNC systems.
