摘要：
In this paper presentation the result of application of time-frequency of the measured overvoltages applies short time Fourier transform and continuous wavelet transform. The analysis based on the Fourier transform renders it possible to extract the information regarding its spectrum variance in time domain from the noise. The results gained from the application of the above analysis give the grounds of the identification of overvoltages on the basis of the frequency patterns.
