Harmonic characteristics of lighting loads

Abstract

An experimental work was undertaken to study the harmonic pattern of various lighting loads in use. A portable power quality meter, Fluke 435 connected to an experimental rack was used as the measuring devices. The logger was programmed to capture essential power data in a set of harmonic load bank such as compact fluorescent lamps (CFL), electronic ballast fluorescent lamps (T5), magnetic fluorescent lamps (MFL), T8. The results show that the level of harmonic distortions is dependent on the numbers and types of loads connected to the 240V receptacles and significant differences observed in the measured active power and engrave values.
