FIELD: electricity.
SUBSTANCE: remote acceptance of acoustic signals is carried out, which accompany partial discharges arising on equipment defects, a signal envelope is identified, and its spectral analysis is carried out, at the same time the spectral analysis is carried out in the range of frequencies of up to 1 kHz, defining the availability (or absence) of a row of serial peaks with frequency multiple to 50 Hz in the spectrum.
EFFECT: provision of the possibility to determine a type of a signal source.
