摘要：

The article analyzes the diagnostics of a high-voltage power transformer by means of an acoustic camera. It is one of the basic diagnostics and monitoring of remote measurement and analysis of acoustic emission. The high-voltage power transformer generates acoustic emission, thanks to which we can analyze the operating and fault states of the device. The article shows the use of the acoustic camera for operational monitoring and diagnostics of its life through noise from the source of the transformer winding and the ferromagnetic core. We performed measurements of acoustic emission on the traction transformers with parameters 5 MVA, 25/6 kV and 25 MVA, 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.
