It is well known that human safety regardingelectromagnetic contamination due to the presence ofelectrical devices in residential areas, like transmission ordistribution lines, substations and transformers is imperative.These devices contribute to residential or industrialelectromagnetic field exposure, which can be correlated withserious drawbacks for the health as childhood leukemia and;cancer.In this context, in order to guarantee people health, it iscrucial that utilities and other stakeholders can attend in asuitable way to these worries, being important for such, levelsof existing electromagnetic fields in their infrastructureanalysis. The main goal of this study is to determine andanalyze the EMF exposure levels of four real-life substationsand their corresponding distribution feeders (twenty one).With these measurements and estimated ones obtainedthrough the use of commercial packages, comparison withregulatory exposure levels are made. Results are discussed andanalyzed.
