Abstract

Abstract The technology of modernization of acoustic diagnostics of oil-filled transformers is described by connecting an additional diagnostic unit for analyzing the temporal and statistical characteristics of the measuring signal. The algorithm of the block functioning is based on the application of identification measurements technologies and digital processing of diagnostic signals, classification of parameters according to designated signal classes and conclusion of the object state with the name. The results of studies of measuring signal images of transformer diagnostics operated on the basis of «SEVKAZENERGO» JSC are presented.
