Abstract

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.
