Abstract

This paper deals with polymer nanocomposites and their related breakdown mechanisms. Polymer nanocomposites seem to be a very promising alternative to conventional polymers regarding high voltage applications. Some developed breakdown models are discussed as well as the mechanism of treeing in such materials. Treeing simulation results are presented.

Highlights

  • Polymeric materials have been used for a long time in high voltage engineering [1]

  • In polymer nanocomposites the nanoparticles are homogenously dispersed in the matrix in concentrations

  • The interfacial region in the nanocomposites is significantly increased in comparison to microcomposites, due to the nanometric scale of the particles, which means that the augmentation of the interfacial region gives to nanocomposites different and unique properties compared to microcomposites
