The rotor blades are a highly stressed part of the turbine. They require comprehensive protection against outside influences, e.g., lightning currents and surges. This can be achieved with a profound protection concept using DEHN products and constant monitoring.

The protection concept
Product recommendations:
Rotor protection
An integrated protection concept prevents damage to the information and data technology in your wind turbine. In addition, the reliable condition monitoring system keeps you posted about the status of your system - indispensable for operational safety and maximum system availability.

Upward flashes present a risk to wind turbines
Always well-informed
As damage resulting from a lightning strike does not automatically lead to the immediate failure of the wind turbine, it is frequently overlooked.
Upward flashes are particulary dangerous in this context. Their initial long stroke current of just a few 100 A is the major source of damage, e.g., melting on the receptors of the rotor blades.
In the long term, this damage can lead to in system failure.
Due to the low flow of current, standard measuring systems often fail to fully detect upward flashes. DEHNdetect, on the other hand, registers both types of current: impulse current and the dangerous long stroke current.
Your benefit: You prevent expensive maintenance work and long downtimes.
