Abstract

Partial discharge (PD) resistance was evaluated for several kinds of nanocomposites. Following experimental results were obtained. Epoxy is stronger in PD resistance than polypropylene. But the enhancement of PD resistance by nano filler addition is higher for polypropylene that for epoxy. Silica and alumina nano fillers exhibit stronger PD resistance than layered silicate, when they are added into epoxy resins. Coupling agents or modifiers will help increase PD resistance. Similar level of the effect can be obtained for both cases of 5 wt% nano filler added epoxy and of 65 wt% micro filler loaded epoxy. Nano-micro composites are the strongest of all tested specimens as PD resistance. The above two experimental facts can be understood from the concept that the shortening of inter-particle distance is effective to reduce PD erosion
