The Lightning Monitoring System (LM-S) from Phoenix Contact detects and analyzes the number, magnitude, and duration of surge currents caused by lightning strikes. Based on this information, a wind turbine manager can decide whether a service call is necessary. If a large strike occurs, he or she can repair the turbine before damage leads to an unplanned shutdown. Or, if the strike was minor, the manager knows that no immediate action is required. The system includes an evaluation unit with up to three fiber optic sensors. The sensors can be mounted on each blade of a turbine. Used in conjunction with wireless or Ethernet communications, the system provides remote monitoring of the equipment, either with a standard web-based interface or reporting through the control system. The LMS is suitable for new blade and retrofit applications.
