摘要：

Vibroacoustic diagnostics (VM-Vibroacoustic Method) is one of the methods for diagnosing the active part of power transformers. One of the recently published objective method for the detection of transformer unit core damage was based on the analysis of the statistical properties of the vibration signal registered on the surface of the tank of an unloaded transformer in the steady state of vibrations. The GGD vibroacoustic detector of power transformer core damage is based on the relative changes in vibration power as a function of frequency and the generalized Gaussian distribution (GGD). The article shows how to configure the detector in order to reduce the variance at the detector output and speed up the detection.
