The present invention relates to a system for a wind turbine. The system comprises 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. A safety bearing element (104, 104', 104") is mounted to the first wind turbine structure such that the second wind turbine structure is in slideable contact with a contact surface (206) of the safety bearing element (104, 104', 104") 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 (104, 104', 104") comprises an electrical indicating circuitry with an indicating conductor (201), wherein the electrical indicating circuitry is connectable to a wear controller system (205) such that a signal is generatable by the electrical indicating circuitry and transmitted to the wear controller system (205) till the indicating conductor is damaged due to the slideable contact of the second wind turbine structure with the safety bearing element (104, 104', 104"). |
