This paper deals with space charge accumulation of LDPE-based nanocomposites containing graphene oxide as nanofiller. Space charge measurements showed huge charge injection and accumulation in the base LDPE material. In particular, at room temperature a positive charge packet was observed moving rapidly from the anode to the cathode, enhancing space charge accumulation in the insulation bulk. On the contrary, space charge buildup was significantly reduced in nanocomposites with a filler content smaller than 0.1 wt%. Increasing temperature, the base material accumulate much less charge therefore the effect of the nanofiller becomes less evident than at room temperature.

Abstract
This paper deals with space charge accumulation of LDPE-based nanocomposites containing graphene oxide as nanofiller. Space charge measurements showed huge charge injection and accumulation in the base LDPE material. In particular, at room temperature a positive charge packet was observed moving rapidly from the anode to the cathode, enhancing space charge accumulation in the insulation bulk. On the contrary, space charge buildup was significantly reduced in nanocomposites with a filler content smaller than 0.1 wt%. Increasing temperature, the base material accumulate much less charge therefore the effect of the nanofiller becomes less evident than at room temperature.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
