In view of the ice disaster which may be suffered by the overhead transmission line in the South China, to realize the monitoring of icing of transmission lines using UAVs, it has important significance to research the application of image edge detection method. In this paper, the principle of the three kinds of edge detection methods which are Canny operator, Sobel operator and adaptive weighted...
In order to improve the accuracy of on-line application and winding condition assessment of pulse frequency response method, this paper proposes a short time Fourier transform (STFT) algorithm to construct the pulse frequency response curve of the transformer windings, trying to solve the problem of the fast Fourier transform, (FFT) algorithm is not suitable for dealing with transient signal. PSPICE...
