Abstract

This paper deals with hybrid organic-inorganic coatings having the purpose to improve the electrical properties of host insulating materials. In particular, space charge behavior of coated XLPE specimens is investigated here as a function of temperature. Three different nanocoating designs are tested, showing promising results in terms of space charge reduction with respect to uncoated XLPE specimens. This improvement has been associated with the increase of the injection barrier at the electrode/insulation interface provided by the nanocoating layer which acts as a partially-blocking electrode.
