Summary:For proper analysis and mitigation of short duration voltage variations, such as sag (dip), swell and interruption, their characterization in terms of magnitude and duration is essential. The short duration voltage events are quantified by calculating the RMS voltage. Although, there are several methods to calculate the RMS values, no method that can be standardized. This paper aims firstly to investigate the parameters that influence greatly RMS voltage calculations. Secondly, the quadrature method for calculating RMS voltage is utilized for power quality events detection. The quadrature method has been examined on several voltage events, such as sag, swell and interruption voltages. The results of the utilized method have been compared with those of conventional methods. The results demonstrate the superiority, accuracy, and robustness of the quadrature method for all cases considered.
