Wind power plants

Exposed wind power plants, such as offshore wind parks, are particularly at risk of lightning strikes. In such systems, complete lightning protection is generally very difficult to implement, even impossible. The lightning monitoring system is ideal for such cases.

The figure shows the arrangement of the individual system components in a wind power plant. A sensor is mounted on each lightning arrester of the vanes. The evaluation unit is located in a control cabinet in the hub. The signals are transmitted between the sensors and the evaluation unit via fiber optics. The Ethernet connection to the central controller is established via slip rings between the gondola and the observation deck. The evaluation unit works with 24 V DC.
If required, the remote contact can be connected to the controller. This makes it possible to signal every lightning strike or evaluate the number of events.
