This research work investigates the effect of inclusion of small amount (0%, 2% and 6%) of natural Nano fillers on the internal field properties and discharge characteristics of polypropylene films. 3D Models are built to simulate field properties and internal charge in natural nanofilled dielectric and insulation. Significant improvement in permittivity and space charge accumulation behavior has been reported by incorporating nanofillers into base polymer. Internal discharge causes gradual deterioration of a dielectric material and may cause failure of the sample. So, modeling and simulation of internal field distortion in nanodielectric is of great interest. Simulated results were compared with real data. Numerical computation and evaluation were done on properties.
