ABSTRACT:
Disclosed are a method and an apparatus for reducing vibrations generated in a stationary induction apparatus by detecting the vibration and by applying a vibration applying force capable of suppressing the detected vibrations to the stationary induction apparatus by at least one vibration applying device, in which the phase and amplitude of the vibration applying force of the vibration applying device are successively and repeatedly adjusted so as to decrease the sum of squares of the respective amplitudes of vibration detected by the vibration sensors. A calculation for obtaining the sum of squares of the detected amplitudes of vibration and the control of the phase and amplitude of the vibration applying force based upon the calculated sum of squares may be carried out in accordance with a program stored in a microcomputer.
