Abstract :
In this paper, a mother wavelet suitable for processing the transient signals of power systems is constructed according to theory of wavelet analysis, and the improved recursive wavelet transform (IRWT) is presented in order to meet the real-time demands of analyzing power system signals. At the same time, research work is carried out to detect the transformer inrush current. IRWT has been used to analyze transformer inrush current generated by PSCAD and is proved both effective and feasible
