The poor power quality causes many problems for affected loads such as instabilities, malfunctions short life time etc.Power line disturbances are mainly caused due to voltage sag, voltage swell,outage and harmonics. These disturbances need recognition and classification. A wavelet based decomposition of the disturbances using norm entropy and pattern recognition by Probabilistic Neural Network has been described.
