This paper deals with space charge characterization of LDPE nanocomposites containing graphene oxide as a nano filler. Space charge was evaluated by using the pulsed electro acoustic technique at 50 kV/mm and at 25°C, 70°C each. Experimental results showed that massive space charges were injected and accumulated in the raw LDPE specimens. Specimens containing graphene oxide, on the contrary, show less amount of accumulation than raw base resin. This results in a smaller electric field distortion, which provides beneficial effect for reliability of electrical insulation. |
