Resumo

This paper proposes a method to select an appropriate mother wavelet for the frequency analysis of electrical transient signals, based on the wavelet properties and considering the needs of the application case. The Wavelet Packet Decomposition (WPD) was used to analyze wavelets as filters and to quantify the information leakage by evaluating the performance of different families included in the Matlab's libraries. To validate the method proposed, an application case is presented where the effective value (RMS) is estimated for a transient signal. The selection method used provides a clear scope on how to exploit the wavelet properties to select the appropriate one depending on the particular application. [PUBLICATION ABSTRACT]
