Screen Conductor Impact on Residential Exposure to Low Frequency Electric and Magnetic Fields

Abstract:

In southern Equator, lower-voltage distribution electric lines are generally built in neighborhoods, being potential sources of exposure to magnetic and electric fields for humans, which could produce adverse effects. Residential and industrial exposure to low frequency electric and magnetic fields generated for utilities and their elements has been associated with possible health effects. In this context, it is important study alternatives in order to mitigate these levels of magnetic and electric field produced by their infrastructure. The aim of this work is to analyze the influence of screen conductors on values of magnetic and electric field, to which utilities worker are exposed. The exposure-mitigation method is estimated thought the placement of screen conductors on distribution feeders, which are simulated by using student version Quickfield software. Depending on the exposuremitigation response, screen conductors in vertical and horizontal topology were modelled, considering four study cases. Two topologies with and without screen conductor, which is located at the bottom of the distribution feeder.
