“…The oil-immersed power transformer is an essential equipment of the power system for power conversion, distribution, and transmission [1]. It is generally accepted that the remaining life of the transformer is mainly determined by the aging condition of the cellulose insulation [2]- [8].…”

“…Then, establishing the quantitative relationship between these feature parameters and insulating states, and, finally, the insulating status of the oil-immersed insulation can be evaluated by the quantity relationship. Existing studies [11,12] indicated that the insulation conditions of power transformers could be affected by various factors, such as moisture, thermal, oxygen, and acids.…”

“…As for the establishment of the quantitative relationship between feature parameters and the insulating states, the traditional methods (such as fitting analysis [12]) achieve it by using the small number of samples, which were faced with the limitation of simple classification (diagnosis) basis, no generalization ability, and difficulty in extrapolation. Fortunately, the support vector machine (SVM) combined with the genetic algorithm (GA) can be utilized to overcome these issues.…”

“…The insulation performance of the oil-immersed power transformer affects the operation level of the power system. While the insulation performance is mainly determined by oil-paper insulation [1]. The deterioration of insulation oil can be solved by replacing oil and filtering oil, but no effective measures have been put forward to solve the deterioration of insulation paper (cellulose insulation).…”
