Abstract :
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 and space charge distribution in XLPE/MgO nanocomposite (MgO nano-filler mixed with Cross Linked Polyethylene) material are reported. Investigations on packet like charge, observed earlier in LDPE, are also made both for XLPE and XLPE/MgO nanocomposite materials. The results indicate the suitability of XLPE/MgO nanocomposite material for HVDC insulation.
