Abstract
Low density polyethylene (LDPE) and nanosilica (SiO2) composites may offer many improved mechanical as well as electrical performance compared to a virgin LDPE. This study focuses on analyzing the partial discharge characteristic of LDPE nanocomposites. Different weight percentages (from 0 to 8wt%) of silica (SiO2) nano particles were introduced as fillers into the LDPE base. The laboratory prepared nanocomposite samples were subjected to electrical stress or aging using the familiar CIGRE Method II setup. Partial discharge pulses were counted for both polarities for upto 60 minutes stress duration. The results show that the PD number of the samples is positively affected by the presence of nanosilica filler when the filler content is above 4wt%. The PD number of a virgin LDPE reduces to half when 8wt% of nanosilica filler is added irrespective of the PD polarities.
