This paper review the study of harmonics present in the system and harmonics filter of primarily used in electrical system. CFL loads Arc furnaces, converters, adjustable speed derives, switch mode power supplies and PWM modulated drives etc. are some of the non-linear loads that generate harmonics. In order to overcome harmonic related problems, passive filters have been used for a long time. The main aim of this paper is to monitorvarious power quality parameters of real time CFL load using power quality analyzer fluke 435 and designing of passive shunt type filter in the distribution system for harmonic mitigation of the load used in analysis.
