<p>The present invention relates to a system for reducing a local vibration of an electric transformer, and more specifically, to a system for reducing a local vibration of an electric transformer comprising a piezoelectric element which generates a vibration having a pulse opposite to a vibration frequency in a vibration portion so as to reduce a local vibration generated from an outer box of the electric transformer. The system for reducing a local vibration of an electric transformer of the present invention comprises: an accelerometer disposed in the outer box of the electric transformer to measure a locally detected vibration frequency; a vibration control unit for generating a phase frequency signal opposite to the vibration frequency measured by the accelerometer; and a piezoelectric element attached to the outer box of the electric transformer to generate a vibration according to a frequency signal transmitted from the vibration control unit.</p> |
