摘要：
The space charge characteristics of insulation paper are crucial under direct current. Thus, improving the space charge behavior of insulation paper is essential. In this study, a nanostructure AlOx film was coated on the surface of insulation paper via RF magnetron sputtering. The space charge distribution was measured using a pulsed electroacoustic instrument. After coating with nanostructure AlOx film, the calculated characteristics showed that space charge accumulation in the samples decreased, and the trap density on the surface of the insulation paper also decreased. Results showed that using the nanostructure AlOx film to improve the space charge performance of insulation paper was feasible and effective. (C) 2018 Elsevier B.V. All rights reserved.
