To understand basic electric properties of nano-sized magnesium oxide (MgO) / low-density polyethylene (LDPE) nanocomposite materials, the temperature dependence of breakdown strength and the space charge up to the breakdown has been investigated under DC ramp field. At temperatures at which these investigations were carried out, DC breakdown strength of the sample with the MgO nano-filler (hereafter,...
It has been proved earlier that electric properties of polymer insulation can be improved by addition of nano-sized inorganic filler. These materials have attracted a lot of attention. With the addition of nano sized MgO filler in Low Density Polyethylene (LDPE), several improvements in material properties were observed and were already reported. In this paper, investigations on the volume resistivity...
