Oil Conductivity Estimation of Transformer Insulation by Switching Impulse Application
IEEE Transactions on Dielectrics and Electrical Insulation(2022)
摘要
This article discusses an advanced method for estimating dc conductivity of oil using parameters evaluated under switching impulse voltage application. Firstly, the effectiveness of switching impulse application for assessing the condition of oil–paper insulation is investigated. Thereafter, the evaluated parameters under switching impulse voltage are fitted by Havriliak and Negami (HN) model for ...
