要約(日本語): Partial discharge (PD) formation is an indication of the insulation degradation which usually shows the presence of incipient faults. The development of PD gives rise to phenomenons such as surface tracking, electrical treeing, etc. which permanently paralyse the insulation. Hence, the detailed PD study helps to analyse the health of insulation. With the latest development, the polymer nanocomposites have proven to be effective towards the PD mitigation which may extend the service lifetime of cable. As XLPE is widely used for high and extra-high voltage cables, the PD study of its nanocomposites has received the attention of researchers. However, the role of different testing conditions such aspoint of voltage application, electromagnetic shielding, and different electrode configurations on the PD measurement remains obscure. With this context, this article presents the comprehensive PD study of XLPE/Silica surface-modifiednanocomposites with 0, 1, and 2 wt % of nanofiller for 3 - 5 samples of each wt %. It is observed that the PD study done on single sample may mislead the result analysis and the optimal wt % of nanofiller. Also, the location/positionof sample where the electrical field is applied plays an important role in the conclusion of PD study. Hence, the present study suggests that the PD analysis must be done by considering the aforementioned external parameters which mayimpact its outcome. In addition, this article includes the electrical field distribution around the different electrode configurations used for this study using COMSOL Mutliphysics software.
