Resumo
The advancement of technology and power electronics has allowed a strong advance in large-scale production of electronic devices, which are incorporated into existing electrical systems, in most cases, so there is a change scenario in the type of interconnected load to the electricity distribution system. However,
these devices can cause changes in the behavior of system components,
caused by harmonics that can result in various damages to electrical
equipment.
These devices are attractive to consumers, as they offer the opportunity to
consume less electricity, as in the case of lamps with active power less than
conventional by more than 50%. The electrical characteristics of these devices
must be better known so that the feeder circuits can be correctly
dimensioned, as well as strategies to solve possible problems arising from
unwanted effects. In this context, this work constitutes an analysis,
performing confrontations between data obtained from traditional and more
modern (“efficient”) devices, in a lighting system in the industrial sector.
Among traditional devices, this research addresses fluorescent and mercury
vapor lamps and, in the case of modern lamps, LED. In this sense, case
studies are presented, with different types of technologies, which allow
obtaining indicators of the power quality, with satisfactory precision and
reliability. It is important to point out that the data referring to the
experimental part were collected in an industrial environment, with the
purpose of providing a qualitative and quantitative analysis, with the best
possible fidelity.
