Effect of graphene oxide (GO) in improving the performance of high voltage insulator

Abstract

Research work of polymer nanocomposites in high voltage insulator becomes interest nowadays. Polymer based and nanofillers are the core components in polymer nanocomposites. In previous works, by adding such a big amount of nanofiller it will enhance the electrical and mechanical properties of polymers. However as for today, a little percentage of nanofiller concentration could dramatically enhanced the properties of the polymeric material. Partial discharge in insulator material is one of a big issue in high voltage system that leads to electrical degradation and thermal losses. Recent research of graphene oxide (GO) nanofiller has brought to this project interest. Hence, this work focused into the development and simulation of PMMA (poly methyl methacrylate)/GO nanocomposites followed by PD test according to CIGRE METHOD II. The PMMA/GO and pure PMMA was synthesized by using radical polymerization and solvent dissolution method meanwhile simulation process was conducted using COMSOL Multiphysics software. From this work it could be noticed that the PMMA/GO has better performance.
