| Research Abstract |
In order to clarify the applicability of nanocomposite to DC electrical insulating material, various electrical characteristics and DC dielectric breakdown mechanisms were investigated. It was revealed that MgO/LDPE nanocomposite was a superior DC electrical insulating material, even under the high electric field, which had a lower electrical conduction current and higher DC breakdown strength. It was indicated that a role of MgO nanofillers on the DC breakdown mechanism was a trapping effect of homo space-charge, which could reduce the conduction current and enhance the DC breakdown endurance. Furthermore, an effective nanostructure to electrical insulating material was investigated. It was revealed that introduction of nano-porous structure to alumina/epoxy composite could lead the lower permittivity insulating material.
