摘要：
The article presents the results of scientific - research related to the detection of partial discharges (PD's) in the bushings using the acoustic emission method (AE). The study was conducted in laboratory conditions using two models of culverts: paper - oil insulation (OIP) and permanent isolation (RIP). Analysis of the recorded signals were carried out in the field of time - frequency using: short-time Fourier transform (STFT), continuous (CWT) and discrete (DWT) wavelet transform. (Detection of partial discharges in transformer insulation bushings using acoustic emission method).
