Modeling and behaviour of partial discharge in nanocomposite materials

Partial Discharge (PD) behaviour in electrical apparatus leads to identify the degradation of insulating materials. This paper provides an analysis of Electric Field (E-Field), Electric potential distributions and Temperature analysis of the nanocomposite materials. The ultimate aim of this simulation studies are carried out to improve the breakdown strength of the nanocomposite materials for long term performances. The major factors that governs the performances of the insulating materials is E-Field and Electric potential distribution which leads to PD and temperature rise which reduces the breakdown strength of the materials. The analysis are performed by modeling the nanocomposite materials in two dimensions (2D) using Finite Element Method (FEM) with nanoparticles of different size for different combinations. According to the results, Polycarbonate (base material) with nanoparticle (SiO₂) of 5% size when compared to base materials shows better performances and nominal temperature rise.
