The longitudinal breakdown strength of Interfaces is low because combination of two solid dielectrics enhances the risk of cavities and moisture at the interfaces. This paper presents the measured results of AC 50Hz breakdown voltage test of XLPE - XLPE interfaces assembled either under water or in standard laboratory conditions in air. A theoretical model for the voltage drops across contact spots and voids is proposed for both dry and wet interfaces. The model utilizes the estimated void… CONTINUE READING
