Abstract

Space charge accumulation in insulation materials indicates to conduction current through a dielectric material and it is important to know as well as possible the amount of charge stored in the dielectric. In this research, space charges tests aredone to distort the local electric fields, high-field conduction and breakdown phenomena in thin films of Polyvinyl Chloride nanocomposite insulation materials. Therefore, space charge characteristics have been investigated by pulsed electro-acoustic (PEA) system for thin thickness of Polyvinyl Chloride nanocomposite materials, which filled with different separate nanoparticles like Clay, and Fumed Silica, from the experimental tests carried out it is noticed that adding Clay and Fumed Silica to Polyvinyl Chloride changes its breakdown phenomena. Thisresearchaims to study the effects of types and concentrations of nanoparticles on space charge accumulation in Polyvinyl Chloride nanocomposites and illustrates which fillers that enhance Polyvinyl Chloride industrial applications.
