摘要：
The article deals with an on-line non-contact measuring method for the analysis of transformer operation by measuring acoustic, noise and electromagnetic emissions. The electric non-rotating machine generates electromagnetic and acoustic waves, by means of which it is possible to analyze not only operating states but also its possible fault states.We performed measurements of acoustic emission on the traction transformers 25/6 kV and 110/3 kV that were in real operation. We studied the spatial distribution of the acoustical field as well as its spectra. Preliminary results have shown that acoustic analysis may be a useful alternative option for high-power transformer's health condition.
