Harmonics from household equipment and different lamp technologies

This paper presents the results of a set of measurements to study changes in harmonic emission from a domestic customer due to the introduction of energy-efficient lamps (CFLs and LED lamps). During this study, measurements have been performed of the emission from different combinations of domestic devices in combination with different kind of lamps. To study harmonic emission, three different states has been deeply studied, likely, high consumption and lamps-only states, where different household device combination together with lamps were connected. Overall, the measurements confirm the conclusion that there is some increase in harmonic emission due to the replacement of incandescent lamps by CFLs and LED lamps, but that there is no reason for concern.
