Electrical conductors (20,22,24,26) are set out along the length of a rotor blade (10). They begin at a rotor blade connection and run in the lengthwise direction of the rotor blade and back to the rotor blade connection. A detector (16) records the electric resistance of the conductors and links to an evaluating device that evaluates electrical resistance. An independent claim is also included for a wind energy installation with a rotor blade according to the present invention. |
