Abstract This research investigation was performed to seek the bio-based alternative for the liquid insulator in transformers. The current investigation aims to examine the effect of oil rancidity on the dielectric strength of bio-based oils along with the other preliminary examinations like fire point, flash point, and viscosity. Sunflower oil portrayed the notable performance under all the tests that were conducted. The exposure to the conditioned atmosphere uncovered the presence of a huge variation in DBV of bio-based oil the affirming that the rancidity of oil degrades the insulating ability of the oil. The multi-objective optimization tool MOORA (Multi-Objective Optimization based on Ratio Analysis) was utilized to optimize and select the best oil sample. Upon considering the outcome of all the tests performed and MOORA, sunflower oil was ranked first.

采用MOORA法优化生物基液体变压器绝缘子

摘要 本研究旨在为变压器中的液体绝缘子寻找生物基替代品。目前的调查旨在检查油酸败对生物基油介电强度的影响以及其他初步检查，如燃点、闪点和粘度。向日葵油在进行的所有测试中都表现出显着的性能。暴露于调节大气中发现生物基油的 DBV 存在巨大变化，这肯定了油的酸败会降低油的绝缘能力。利用多目标优化工具MOORA（基于比率分析的多目标优化）来优化和选择最佳油样。考虑到所有测试的结果和 MOORA，
