Comparison of Current Harmonic Emission by Different Lighting Technologies

This paper presents an analysis of current harmonic emission form different lighting technologies in the residential network. Lighting consumes a significant share of total electricity consumption. The governments are making policies to promote the usage of energy-efficient electrical appliances. The energy-efficient lamps are now replacing the inefficient incandescent lamps to reduce power consumption. These lamps encompass non-linear circuits and reduce the power quality of the distribution network. The large scale penetration of energy-efficient can have an enormous effect on power quality issues in the grid. This study provides an estimation of harmonic current emission by the gradual replacement of incandescent lamps with compact fluorescent and light-emitting diode lamps.
