Abstract: The power quality is deteriorating day by day due to the extensive use of power electronic based devices which have non linear relationship between voltage and current. The major domestic and industrial non-linear devices are major source of harmonics in power supply network. The harmonic is measured in various indicators but Total Harmonic Distortion (THD) is one of the popular harmonic indicator. In this paper detailed harmonic analysis is carried out in respect of THD in load current of non linear devices. The THD values of all the non-linear loads are analysed and evaluated in current spectrum with the help of Power Harmonic Analyzer.
Keywords: Harmonic, Non-Linear Load, Total Harmonic Distortion (THD), Power Quality
