Abstract

Corona and gap type discharges occurring at high voltage hardware generate appreciable electromagnetic interference (EMI). This work is concerned with the level of interference generated at substations located in the Central Region of Saudi Arabia. The contribution of substation hardware to the overall power system EMI was found by measuring the EMI frequency spectrum under a power line near and away from the substation. Two areas in the central region namely Riyadh and Qassim, were considered. Some differences were observed between the substations in the two areas. The results of these measurements are analysed in the paper.
