对传统矿物油和合成酯MIDEL 7131两种不同类型的热老化油纸的空间电荷效应进行了测试和比较。结果表明，在老化过程和后续实验之间需要几天的静置时间才能达到水分平衡。随着热老化的进行，油纸样品中注入了更多的电荷，但油和油纸电导率的增加可能会导致电荷积累的减少。最大。不同油纸样品的电场畸变率表明，MIDEL油纸的绝缘性能可能优于矿物油纸。
Space charge effects in two different types of thermally aged oil-paper which are traditional mineral oil and synthetic ester MIDEL 7131 immersed paper, were tested and compared. The results show that a few days standing time between the ageing processes and following experiments are necessary to achieve water equilibrium. With thermal ageing conducted, more charges were injected into the oil-paper sample, however, the increase in conductivity of oil and oil-paper may lead to the decrease of charge accumulation. The Max. electric field distortions of different oil-paper samples indicate the MIDEL oil-paper may have a better insulation performance than that of the mineral oil-paper.
