| Abstract |
Epoxy resin is widely used in high voltage insulator material because of its high dielectric
strength. Electrical tree phenomena are one of an electrical insulation degradation. It is easily initiated
due to the distorted high electrical field. In this study, graphene nanoplatelets (GNPs) with the
contents of 0.003-0.010 wt.% (2.6-8.8 mg) were filled into epoxy resin to improve electrical tree
inhibiting ability. Treeing experiments were conducted at a fixed voltage of 15 kV, 50 Hz. LCD
digital microscope was used to observe the electrical tree inhibition of GNPs in epoxy resin. The
digital image of insulators sample was then analyzed by MATLAB program. The percentage of
electrical tree damages of GNPs content of 0.007 wt.% was found at 2.75 %. Experimental results
showed that electrical tree has propagated from main branch tree to many small branches. The
distributed electrical tree around the main branches occurred after the addition of GNPs. Filling GNPs
content of 0.005 wt.% will result to a complex branch tree structure with much longer branches than
others. Nevertheless, the average tree length was inhibited at the GNPs filling contents of 0.003 to
0.007 wt.%. |
