The method involves detecting vibrations of the winding of the generator (2), during the operation of generator, and transforming the signals of the vibrations into the frequency range. Transformation of multiple individual vibrations from the frequency signals into the modal range is carried out, while determining the deviations of modal forms and/or individual bar vibrations in relation to a reference response. The operating parameters of the generator, such as active power, reactive power and/or temperature, are further detected for monitoring the vibrations. An independent claim is included for an apparatus for monitoring winding head vibrations of generator. |
