Abstract

This paper presents the results of a set of measurements to study changes in voltage harmonic emission in LV grid due to the introduction of energy-efficient lamps. The paper involves measurements in an urban area performed in the north of Sweden. Measurements of voltage harmonic were performed before and after replacing all existing (mainly incandescent) lamps with LED lamps in all 12 houses belonging to the same urban area. The total power of all lamps was reduced from approximately 2300 W to 450 W, per house. All new lamps were low-power-factor lamps. In this paper it has only been shown the results for two individual houses over the twelve that changed their lamps. Those results are then compared with the standard EN 50160 in order to foresee the voltage impact after changing to LED lamps.
