This paper deals with the investigation of partial discharge (PD) resistance of some epoxy-resin nanostructured materials. The base material is modified by inorganic nanofillers, i.e., silicates (SiO2) and titanium oxide (TiO2), with different filler content (ranging from 10 to 25 % in weight). Results coming from PD acquisition and surface erosion measurements carried out during aging tests allow some quantities to be extracted, which can be related to surface degradation due to PD. These results show that nanostructured materials, in general, can withstand better PD activity than the base material, particularly the one containing SiO2 with 10% in weight.

Abstract
This paper deals with the investigation of partial discharge (PD) resistance of some epoxy-resin nanostructured materials. The base material is modified by inorganic nanofillers, i.e., silicates (SiO2) and titanium oxide (TiO2), with different filler content (ranging from 10 to 25 % in weight). Results coming from PD acquisition and surface erosion measurements carried out during aging tests allow some quantities to be extracted, which can be related to surface degradation due to PD. These results show that nanostructured materials, in general, can withstand better PD activity than the base material, particularly the one containing SiO2 with 10% in weight.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
