The main focus of this article is to analyze the profile of LED lamps, tubular and compact, present in Consumer Units from groups A and B. The current technological advances led to increasing use of electronic loads in all sectors, mainly in residential and commercial consumers. In laboratory measurements using LED lamps, it was observed that the reactive power flow injected into the bar is equivalent or greater than the power flow consumed by the lamps, thus influencing the power factor of the electrical system. This paper presents measurements on electronic loads, composed of LED lamps, common in Consumer Units and analyzes its influence on the charging system and power quality.
