几个世纪以来，石油在许多应用领域（包括运输、家庭和电力）的能源需求一直占主导地位。矿物油作为变压器中重要的绝缘材料已经使用了150多年。电力系统设备中的矿物油应用可能对环境造成潜在危害，特别是在运行期间发生任何事故时，如Transformer爆炸，可能导致油溢出到土壤或水流中。由于人们对石油资源和环境问题的关注，具有生物降解特性的替代绝缘油引起了人们的广泛关注。本论文研究了一种矿物油和一种植物油的介电性能，并研究了加速热老化对其介电性能的影响。由于其影响其介电性能，如击穿电压，介电损耗，和相对介电常数，湿度的油被测量沿着老化过程。实验结果与以前的研究进行了比较，表明在这项工作中获得的测试结果与以前的工作相比，大部分。
The world’s energy requirement has been dominated by petroleum oil for centuries in many application fields, including transportation, household, and electricity. Mineral oil as an important insulating material in transformers has been used more than 150 years. Mineral oil application in power system equipment can be potentially hazardous to the environment especially when there are any incidents during operational time like transformer explosion which may cause a spill of oil to the soil or water stream. Due to the concerns about the deducing petroleum resources and the environmental issues, the alternative insulating oil with biodegradable characteristics has been attracted lots of attentions for a couple of decades. In this thesis, the dielectric properties of a type of mineral oil and a type of vegetable oil were investigated, and the effect of accelerated thermal aging on their dielectric properties were studied as well. Since it affects its dielectric properties, such as breakdown voltage, dielectric dissipation, and relative permittivity, the humidity of oil was measured along the aging process. The experimental results were compared with those from the previous research, showing that most of the test results obtained in this work was comparable with the previous work.
