Abstract

Electric and magnetic field measurements around overhead and underground power lines have been performed extensively within a transmission and distribution electric grid. Measurements have been performed at different heights of the human body close to such transmission and distribution power lines that operate at a frequency of 50 Hz, at different currents and at three different voltages of 11, 66 and 132 kV. These measurements were performed in an attempt to firstly verify that the existing measurements fall within the signified guidelines for electric and magnetic field exposure, published in 1998 by the International Commission on Non-Ionizing Radiation Protection. Furthermore, and most importantly, were used to validate/develop a model capable of predicting the magnetic field produced in both overhead and underground transmission and distribution power lines using experimental measurements. This is achieved by establishing a linear correlation between the current load of one of the two three phase circuits and the magnetic field, in an attempt to predict the magnetic fields produced in power lines using the SCADA system at overloaded periods.
