| Abstract | ||||
| Electrical treeing is a pre-breakdown mechanism, and is the responsible for the long-term degradation of polymer insulation. This paper has been enhanced both the life-time of tree propagation to breakdown and the tree growth rate of electrical tree propagation by adding various amounts of nanoparticles as Clay, Silica, ZnO, and Al2O3 to various industrial materials CT200 Epoxy Resin, and LY/HY-5052 Epoxy Resin. This research has focused on the development of nanocomposite materials with electrical tree growth resistance superior to the unfilled matrix, and has stressed particularly the effect of filler volume fraction on the breakdown resistance. Finally, this research aims to present a systematic and comparative study about the effect of adding nanoparticles to dielectric insulation, and to understand the role of these nanoparticles, Clay, Silica, ZnO, and Al2O3 particles in the CT200 Epoxy Resin and LY/HY-5052 Epoxy Resin which can made significant improvement in breakdown resistance, life-time of insulation and decreasing the tree growth rate of electrical tree propagation. | ||||
