摘要：
The article presents the results of attempts made to develop a non-invasive diagnostic method of a technical state of a transformer's core based on an analysis of mechanical vibrations registered during the start-up of the transformer analyzed. The analysis of recorded vibroacoustic signals was performed my means of Continuous Wavelet Transform (CWT) for three different operating cases: the transformer with no core defect, the transformer with loose screws of the magnetic circuit of the upper yoke and the transformer with completely loosen screws of the beam of the upper yoke and the lower core. (Application of Continuous Wavelet Transform to Analysis of the Vibration Signals Measurement with Modified Vibroacoustic Method).
