dc.description.abstractThe insulator surface flashover potential increases when a magnetic field with the proper orientation is present at the surface of the dielectric (magnetic insulation effect). In order to observe an obvious magnetic insulation effect, a critical magnetic field has to be reached. Earlier studies have shown that the insulator surface flashover potential increases after a vacuum spark discharge surface treatment. This research is to study the magnetic effect on a treated sample. A cylindrical Lexan sample and brass plate-plate electrodes are used in this study. Small, cubic, lightweight permanent magnets which can produce up to 0.38 T magnetic fleld at their surface are arranged in proper configuration to create a magnetic field along the sample surface. Three experimental configurations are used in this experiment. This thesis first gives some background information about the surface flashover, then introduces the experimental setup and procedure. Finally results are presented and explained.
