“…Harmonics produced by saturable devices are generated due to iron saturation, which is the case for transformers, machines and fluorescent lamps (with magnetic ballasts) [16,17]. On the other hand, power electronic devices, as in the case of voltage source converters, switch-mode power supplies, power electronic converters and fluorescent lights (with electronic ballasts), which are some kind of power electronic devices [18][19][20]. The distortions in the power network can influence negatively the functions of some equipment, making them respond in an unpredicted manner when subjected to multiple frequencies [21][22][23][24].…”

This paper evaluates the impact of voltage distortion on the electrical quantities measured by revenue meters and the influences on the electrical energy billing. This is done through an experimental setup, which combines the following variables for the first time in an experiment: different total harmonic voltage distortion (THDv) levels; among these levels, different harmonic profiles; and different loads. A programmable alternating current (AC) power source was used in the laboratory to apply voltage signals in three electronic loads: a compact fluorescent lamp (CFL) and two light emitting diode (LED) lighting devices for which voltage signals with THDv 4.9%, 18.8% and 24.5% have been applied. All applied signals contain one or more harmonic order more commonly found in the low voltage grid (3rd, 5th and 7th). For these analyses, a power quality analyzer and a revenue meter were used. The results show that significant and diverse effects on the electrical quantities of individual loads will occur with different THDv levels and harmonic profiles. Comparing with a reference case (sinusoidal condition), when a distorted signal was applied, for the same THDv level, some parameters remained numerically the same, some have improved and some have become worse. This study shows that the effects of combination of the variables such as different THDv level with different harmonic profiles on electrical quantities of loads are not as clear as the effects of considering only one variable. The results of this paper shed light on such effects.

Luiz Carlos Pereira da Silva, for all the guidance and support over the last years.Additionally, I would like to thank my colleagues from Brazil and Denmark, who were always available to make technical discussions, advise me and collaborate during my Ph.D. In particular, I would like to thank few people: Pedro Pablo Vergara Barrios, for all his support and patience at the beginning of my journey, as well as Seyyedeh Newsha Ghoreishi, who welcomed me and my family into her sweet home -I have no words for show how grateful I am for you. Also, still in Denmark, a special thanks to Athila Quaresma dos Santos, a Brazilian friend who I met so far from our country. Finally, I would like to thank Rodolfo Quadros for all the partnerships during the writing process of all the papers. I would like to acknowledge the three universities for all their support in developing this Ph.D. project: Federal University of Mato Grosso (UFMT), where I work; University of Campinas (UNICAMP) and University of Southern Denmark (SDU), these last ones I am so glad for allow me to participate in a dual degree program. Thanks to Karina Schwartz, Luna Larsen, Louise Møller and to all SDU staff team. Thanks also to all scientists and engineers who have contributed to the development of the state-of-the-art as we know it today.Last, but none less important, I thank my family in Brazil, my dad José Carlos, my mom Sandra Perillo, my brothers Rafael and Renan and his respective families, my wife Vivian Petenucci and her family, and my sweet and lovely daughter, Mariana Bressan. I hope you all feel proud of me. Thank you for all."Insanity is doing the same thing over and over again and expecting different results."Unknown author.
