The increasing demand for electricity has led humans to a growing exposure to artificial sources of electromagnetic emission, making it essential to determine the intensity of electromagnetic fields (EMFs), which is subject to the population of a given area. This Letter proposes an analysis of EMF exposure levels and spatial distribution over the region of the input and power circuits of a 230 kV/60 Hz air-insulated substation. For this, measurement protocols were determined based on current standards and from spatial interpolation methods, a contour map was developed, allowing a complete evaluation of the behaviour and levels of EMF throughout the region. The results obtained indicate that exposure levels in this region are below those recommended by regulatory agencies.
