Abstract

Surface Discharge is a typical electrical release that regularly happens on the surface of outside of
insulator furthermore causes the failure in the electrical insulation system. One of the reasons for surface discharge is the
vicinity of high voltage stress. Experimental work has been carried to inspect the surface discharge qualities on insulating
materials. The IEC (b) electrode configuration had been utilized to examine the surface discharge phen omena of diverse
sorts of protecting materials. In this paper insulation materials like Flexitherm (class F), Trivoltherm (class F), Lamiflex
(class B), are choose for investigation. Surface discharge intensity and surface morphology of every insulating material
were additionally studied. It is shown that the surface degradation that happen on the specimen, may be brought on by the
surface conductivity & when the surface conductivity of solid insulating material increase the discharges magnitude
intensity also increase this lead to severe surface degradation on the specimens.
