Abstract

In order to understand the relationship between short-circuit impact sound signal and winding deformation of power transformer, this paper carried out transient voiceprint experiment of multiple short-circuit impact of winding. Then, based on this, the winding deformation detection based on BOTDR is discussed, and the frequency spectrum and typical situation of transient voiceprint are analyzed. Finally, a new comprehensive analysis method of transient characteristics is proposed. Through the analysis, it can be seen that this method is accurate and can be applied to the winding state evaluation.
