Abstract :
This paper presents a low-cost virtual instrument for detection and analysis of voltage notches in voltage supply using wavelets. A simple wavelet decomposition tree has been used for detection and analysis of the two main features of voltage notching: the transients associated with the beginning and the end of the commutation notches and the stationary high-frequency components of the spectrum of the signal. The results obtained show the performance of the method proposed in the detection and analysis of the time-frequency characteristics of voltage notching.
