Abstract :
This work presents some electrical characterisation performed on nanocomposite materials. These compounds were obtained by the dispersion of inorganic nanoparticles into a matrix of High and Low Density Polyethylene (PE). The nanocomposites have been prepared by melt compounding using a twin screw extruder. The dielectric breakdown strength of the nanocomposites was investigated using AC progressive-stress tests at a rate of voltage increase of 500 V/s. Specimens were subjected to ageing under corona discharges using the standard electrode configuration of the CIGRE method II. The breakdown and the resistance to surface discharges in PE/SiO2 nanocomposites were studied.
