Techniques for Localizing Sources of Pulsed Electromangetic Interfering Waves in Power Equipment

Abstract

A pulsed electromagnetic interfering wave may be emitted from power equipment owing to a discharge phenomenon, which may occur at a faulty point, such as an unintended narrow gap between metal supports or a deteriorated insulator. Therefore, it is necessary to localize the electromagnetic interference source or estimate its direction of arrival (DOA) effectively to reduce maintenance and eliminate its effect on communication systems.
