ZGLJ-B3 Multi-channel Lightning Monitor of the Wind Power System

   

General                                                                                 
The system can monitor the lightning current information of wind turbine blades subjected to lightning strikes in real time and accurately.

Lightning threatens the safe operation of wind turbines. Therefore, we need to accurately grasp the time, frequency and lightning current characteristics of wind turbines subjected to lightning strikes, for easy evaluation of the effects of lightning protection facilities, and providing the basis for design, reconstruction and insurance claims of lightning protection in the area, to ensure the safe operation of wind turbines. 
The system consists of the lightning current sensor installed in the blades and hubs, lightning monitor, and lightning data management software for the monitoring center.
