Feature analysis of acoustic emission signals in time-frequency representation from partial discharge sources using self-organizing map

Electrical systems throughout the world are experiencing problems with aging insulation. One of the major components, which degrade under stresses, is the paper insulation of a power transformer. In this research work, analysis of acoustic emission (AE) signal patterns due to the occurrence of parti...
