In this paper, nano composites material is produced by adding MgO with particle size of 5 [nm] into epoxy resign using as insulating material of power transformer apparatus and molding part to study the volume resistivity of nano composites used epoxy. We measured the volume resistivity using the High Resistance Meter(4329A) depending on changing the amount of addition and temperature in this experience. In result, we have confirmed that 1.0, 3.0, 5.0 and 10.0 [wt%] as about 2.9, 7.6, 7.5 and 6.1 times increased than virgin. Therefore, the characteristic of volume resistivity was relatively stable as specimen by added 3.0 [wt%] than the others.

In the study the volume resistivity Characteristics of epoxy resin using nanocomposites, nano-comosites are made from insulating material epoxy resin using for power transformer equipment and molding several devices as changing amount of addition of diameter 12 [nm] $SiO_2$, we measured volume resistivity of nano-composites by High Resistance Meter(4329A). As the result of measurement, we have seen the epoxy resin using 1.6 [wt%] nanocomposites was the highest measured at the volume resistivity, and using 0.4 [wt%] nanocomposites was highest stabilized than others according to variable temperature properties.
