Experimental characterization and analysis of low-frequency electric fields in the vicinity of power lines

Abstract EN

The aim of this study is to analyze the behavior of electric field for distribution and transmission lines (30kV, 90kV, 150kV and 225kV), to verify the limits with tolerance thresholds defined by international standards and to respond better to EMC requirements for occupational and non-occupational exposure.

For this purpose, several measurements were carried out at the Society of Electricity and Gas of Tunisia STEG, in order to define the electromagnetic characterization of this field.

The implications of the experimental results are also compared and discussed with new international standards.

The maximum intensities of the electric fields measured for in northern Tunis were significantly lower than the ICNIRP reference levels except for the 225 kV double circuit transmission line.

This last will be used subsequently as a source of disturbance applied to the organs of the human body
