Application of GIS for the Evaluation of Electromagnetic Field Effects for Iraqi 132KV Electrical Transmission System

Abstract

This research endeavors to create the 50Hz electromagnetic field atlas forpopulated urban areas in the city of Baghdad (Iraq). For this purpose, the 3-dimensions numerical model based on finite element method (FEM) with timeharmonic system is used for simulated and modeling electric and magnetic fieldssurrounding the 132kV transmission system. The calculated magnetic and electricfield levels are compared to exposure guidelines given by International Commissionon Non-Ionizing Radiation Protection (ICNIRP). To assign the dangers regions in thecity, the properties of the Geographical Information System (GIS) were used. TheGIS map highlighted visually the unsafe zones and facilitate the extraction of theelectric and magnetic field levels of exposure.
