N2 - Low density polyethylene (LDPE) was melt-compounded with MgO nano-fillers to produce LDPE/MgO nanocomposite. Its partial discharge (PD) resistance was evaluated by using a rod-to-plane electrode system. Erosion depth was measured as an index of PD resistance. Permittivity and tan 5 were also measured to investigate interfacial morphological change due to nanostructuration. It was found that LDPE exhibits the increase in its partial PD resistance, if it is filled with the nanofillers by 1 to 10 phr (parts per hundred parts of resins). It should be noted that marked improvement appears in their content even as small as 1 phr. This tendency also appears for the permittivity of the same nanocomposite, i.e. the permittivity seems to show a minimum point, when nanofillers are added by 1 phr. PD resistance and dielectric properties of LDPE/MgO nanocomposite are discussed in terms of a multi-core model.
