Bibliometric review of the analysis of harmonic losses in public lighting systems.

Electricity supply is fundamental for modern society's existence and development, directly impacting health, safety, education, comfort, and other technological applications. One of the important applications of electric energy is lighting, which allows society to make nights even more productive during the day. With the development of LED technology and a significant increase in luminous efficiency, public lighting has undergone a major transformation and replacement of the technology of High-Intensity Discharge (HID) technology. As it is a switched source, this technology is a type of non-linear load, which raises concerns regarding the impacts of harmonic distortions, which can harm equipment connected to the network and cause power losses. In this way, the present study carried out bibliographic research about the losses of electric energy resulting from the incidence of harmonics in the electrical system through the dissemination of the application of LED technology in the public lighting system, using the materials already prepared and published. In this context, this article aims to research studies on harmonic distortions in the public lighting system to identify gaps and research opportunities. For this purpose, a bibliometric literature review was carried out in the SCOPUS database. Among the results obtained, it was found that harmonic distortions in LED are helpful for research and that there has been an increase in studies focused on the theme over the last 10 years. The present work also showed that there are research gaps to be developed. [ABSTRACT FROM AUTHOR]
