Abstract

A laboratory experiment was set out to detect acoustic signals associated with electrical treeing.. Strong acoustic emission in the 10-15 kHz range is present in initial stages of electrical tree development. Appearance and growth of tree branches coincides with diminishing intensity as well as reduced repetition rate of the sound bursts. During the more advanced stages of electrical tree evolution, until the breakdown point, the sound becomes undetectable. These observations are important if acoustic methods were to be used for condition monitoring of insulation with solid dielectrics, such as in high voltage cable systems.
