  • Wear sensor for a wind turbine
    Patent number: 9593673
    Abstract: A system comprising a first wind turbine structure and a second wind turbine structure, wherein the first wind turbine structure and the second wind turbine structure are rotatable with respect to each other is provided. A safety bearing element is mounted to the first wind turbine structure such that the second wind turbine structure is in slideable contact with a contact surface of the safety bearing element if a distance between the first wind turbine structure and the second wind turbine structure is reduced below a predetermined reference value. The safety bearing element comprises an electrical indicating circuitry with an indicating conductor, wherein the indicating circuitry is connectable to a wear controller system such that a signal is generatable by the indicating circuitry and transmitted to the wear controller system until the indicating conductor is damaged due to the slideable contact of the second wind turbine structure with the safety bearing element.

  • Method of attaching a load sensor to a surface of a rotor blade and rotor blade
    Publication number: 20110217168
    Abstract: A method of attaching a load sensor comprising a support with a number of strain gauges on a surface of a rotor blade is proposed. The method comprises the steps of producing a set of holes with a predefined distance between the holes. Threaded inserts are provided in the holes. Bolts are inserted through the load sensor into the threaded inserts. A rotor blade with a load sensor is also proposed.
