This document presents a methodology for the identification of supraharmonic emissions (current and voltage conducted emissions between 2-150 kHz) at the end-user side of the distribution grid, using low power LED lamps as Equipment Under Test (EUT). First chapter presents a brief classification of power quality disturbances and describes those related to waveform distortion. Second chapter describes the measurement and experimental setups used to assess the supraharmonic emissions from selected EUT. Third chapter explains the methodology for the identification of supraharmonic emissions when EUT perform in single operation, and fourth chapter shows the interaction of such emissions for EUT in simultaneous operation. Along with a set of experimental combinations, supraharmonic emissions and their more relevant metrology aspects are discussed through the text. Results show how voltage and current supraharmonic emissions are (or not) affected by different variations in voltage source, equivalent network impedance, measurement setup and circuit topology of selected EUT. This research is aimed to contribute to the understanding and systematic assessment of supraharmonic emissions, with a special emphasis on metrological aspects and statistical methods for their identification.
