Abstract :
Distortions commonly found in industrial environments are analysed using wavelet theory. Applications such as extracting the fundamental frequency of a nonsinusoidal current signal, or using the ability of compact representation to detect and store nonrepetitive disturbances are presented. A brief theoretical introduction to wavelet transforms is developed and some practical cases are discussed
