ABSTRACT
Transmission lines are considered one of the major sources of magnetic field. In recent years great public concern has arisen because of reports on adverse health effects due to Magnetic fields. The rapid increase of electric energy utilization and ascending geographical growth in the Gulf Cooperation Council (GCC) region led to the reality that utilities need to upgrade and develop existing and new transmission and distribution lines which resulted in the transmission lines to become inside the urban areas. This project is directed to measure magnetic field on existing lines in the Eastern Province of Saudi Arabia. This real measurement have been compared with simulation results and also used to provide a validation of using the simulation software package for design purposes. Transmission lines towers and conductors models are developed from given electrical and geometrical data and used to compute the magnetic fields under, within the right-of-way (ROW) and outside the ROW. Analysis and comparison of measured and simulated fields are used to verify the transmission line model and identify the important magnetic sources and location. The 380 and 230 kV transmission lines designs are selected and studied in terms of their measurement and simulated fields. This project is to accumulate and evaluate the EMF data from these transmission lines, and also to introduce and suggests new data for the EHV lines in the GCC utilities that can be utilized during any future expansion to these utilities.
