Abstract
A method for monitoring a state of a drive train of a wind power plant. The drive train including at least one component which is mechanically connected to a rotating element of the drive train and at least one acceleration sensor connected to the rotating element and located at a distance from a rotational axis of the drive train. The at least one acceleration sensor is configured to rotate about the rotational axis of the drive train at the distance. A signal of the at least one acceleration sensor is sensed in terms of its timing at least one rotational speed of the rotating element and is examined for interference frequencies which correspond to damage in the drive train.
