Abstract

This paper presents an initial investigation on the effect of an external magnetic field on partial discharge (PD) characteristics of voids in solid dielectric media, with a particular focus on statistics parameters derived from the classic phased-resolved patterns. Although it has long been known that high magnetic fields are present in equipment such as power transformers where PD may occur, only a few investigations have been made on the effect of the magnetic field on the discharge characteristics, and in these cases only the point-plane configuration has been considered. In the present study, magnetic fields of up to 128 mT were applied across several voids of known dimensions.
