Description
Summary:Resistive field grading materials is deliberately gaining attention since it shows better performance in steering uniformly electrical properties of high voltage equipment compared to conventional machinery techniques. The key point of these extraordinary materials because its electrical properties that can be tuneable according to material characteristics, composition of chemical elements in the host matrix and significantly influenced from fabrication process. In this research, microvaristor composite was added with silicone rubber at different weight percentage (wt. %) with dimension 50 mm x 50 mm x 5 mm. The selection of this material because it is more robust and less sensitive to a variety parameters such as pressure and humidity. The samples were examined under power frequency voltage at 50 Hz. The experimental results were analysed using Point on Wave (POW) technique and electrical properties for all samples were evaluated at highest applied voltage, 5 kV.
