Abstract

In this paper, various kinds of epoxy based nanocomposites were made and AC breakdown properties of nano-$TiO_2$ and micro-silica filler mixture of epoxy based composites were studied by sphere to sphere electrode. Moreover, nano- and micro-filler combinations were adopted as an approach toward practical application of nanocomposite insulating materials. AC breakdown test was performed at room temperature $(25^{\circ}C)$, $80^{\circ}C$ and $100^{\circ}C$. The result shows breakdown strength about non-filled, nano-scale $TiO_2$, micro-scale silica and nano-$TiO_2$, micro-silica filled epoxy composites.
