Measurement of Power Quality Effects and Energy Efficiency of Various Light Technologies

Abstract

The paper deals with the influence on the power quality of various light technologies and measurement of their energy efficiency (lighting efficiency). A virtual power quality analyzer which enables measurement of all the power components, using the newest power models and definitions, is shortly described. Details of the measurement of harmonics generation by different light technologies are presented. A more realistic approach to the energy efficiency estimation, by the real electrical energy consumption, is proposed. This approach to the energy (lighting) efficiency estimation could be generalized to other domestic appliances, sources of harmonics.
