With advances in energy demand, investments in energy efficiency and power quality are increasingly important. One of the extensively adopted measures is the replacement of fluorescent lamps by LED lamps. This measure contributes to the increase of energy efficiency, but produces a high load of current harmonics, which may cause degradation in power quality indicators of the electric distribution networks, due to the presence of rectification electronic circuits present in such lamps. In this work, several models of LED lamps available in the Brazilian market were tested for harmonic and power factor production, taking as reference the standards Inmetro 389/2014, 143/2015 and 144/2015. Applying the Fast Fourier Transform (FFT) the modules and phases of each harmonic component in the currents were measured. Subsequently, the total harmonic distortion (THD) of the current in each lamp was calculated and the estimated total power factor. The results obtained were compared with the nominal values of the lamps and the circuit of four of the lamps was analyzed. It was verified that only six models out of the twenty-three analyzed had THD below 100% and of the analyzed models, 61% did not meet the nominal technical specifications regarding the power factor, and that Power Factor Correction (PFC) techniques present in some of the models were responsible for adjusting the lamps to the regulation parameters.Downloads
