摘要：
This paper presents a method for vibroacoustic analysis of a transformer in the steady state. The standard approach to this problem has been based on analysis of the vibration frequency spectrum recorded with an accelerometer mounted on the transformer's tank. To improve legibility of measurement results, the paper suggests the analysis method for the relative coefficient of harmonic frequency contents h(norm)(f). The conducted experiment showed that high values of h(norm) within a wide frequency range testify to deformation of windings and degradation of solid insulation.
