Abstract :
The increased sensitivity of power electronics equipment results in high susceptibility of industrial customers to short term voltage variations such as sags and swells. Many utilities are publishing power quality index values to indicate overall quality of their distribution systems. In this study, a real time Power Quality Index Meter that combines the detection of disturbances and the calculation of required power quality indices is proposed. The real time index metering eliminates the need for extended memory and greatly reduces subsequent data processing efforts.
