Comparative study of different residential illumination appliances based on power quality

The main emphasis of this paper is on the power quality based comparison of different house hold illumination appliances. An attempt has been made to measure the THD of different illumination system i.e. Incandescent lamp, Fluorescent Lamp with magnetic and electronic ballast, Compact fluorescent lamp (CFL) and Light Emitting diode (LED). All above illumination system were used for experimental work. An experimental set up were developed to measure THD. The total THD of all the system will affect the power system as a whole. Also the comparative study of basic power quality aspect measured is wattage, luminous performance and power factor of different types of illumination system. The various energy savings fluorescent lamps with core-coil and solid-state ballasts were studied. Fluorescent lighting incorporating solid-state ballasts revealed a larger harmonic content, in the measured current with odd multiples of the fundamental frequency than that obtained for lighting systems equipped with core-coil ballasts. The scope of the proposed work is to focus the harmonics contents from various modern residential illumination system, which deteriorate the power quality.
