Description: Set of limits of electrical properties which allows electrical systems to function in their intended manner without substantial loss of performance is called power quality. Today’s electricity consuming equipment’s are very much sensitive to power quality problems; hence power quality is a growing concern. Problems like, sags and swells, last only for a fraction of a second, but cause severe damage and great loss in the power systems. Hence the detection of the voltage sags and swells is considered very important. The paper presents three algorithms based on a windowing technique to detect sag and swell using a PIC32 microcontroller. Also their comparisons are made. Simulation results using Mat lab are also presented to verify the effectiveness of the proposed methods.
