ABSTRACT
Conventional power systems are designed to operate on sinusoidal power supply. Electric utilities strive to supply consumers with reliable & pure sinusoidal electric power that does not represent a damaging threat to their equipments. Due to globalization, use of nonlinear devices have set the basis for paying considerable attention to the quality of electric power and seriously addressing the issue of current and voltage distortion - called Harmonic distortion. Now a days many devices are introduced to monitor and analyse the effects of harmonics on system and consumer devices. Paper presents the summary of results of survey of harmonics using advanced Power Quality analyser. The aim of survey is to identify the Power Quality levels which need the accomplishment of monitoring to find out the solutions to be implemented.Power Quality indices are analysed at Indian distribution network for various categories of non-linear consumers. This study leads to identify Power Quality level with respect to IEEE Standard 519-1992.
