온도 변화에 따른 Nano/Micro $SiO_2$ 혼합 Epoxy의 체적고유저항 특성

In the study the volume resistivity Characteristics of epoxy resin using nano and micro filler, nano and micro filler are made from insulating material epoxy resin using for transformer equipment and molding several devices as changing amount of addition of diameter 12 [nm] and 7 [${\mu}m$] $SiO_2$, we measured volume resistivity of nano and micro filler by High Resistance Meter(4329A). As the result of measurement, When is micro filler, the volume resistivity continuously increased over 80 [$^{\circ}$].
