Factor analysis is a very popular multivariate statistical analysis method. It can summarize some unobservable factors from the test results which can summarize most of the observed data. The factor analysis suggest the DP, furfuran and CO_X can be divided into insulation aging factor, while the hydrocarbon gas and hydrogen were divided into another group which can be called insulation fault factor. The result of the factor analysis

因子分析作为一种常用的多元统计分析方法，可从众多可观测变量中，概括和推论出少数不可观测的潜变量，用最少的因子去概括和解释大量的观测事实；本文将试验过程中90℃下油中溶解气体、绝缘聚合度、糠醛等参量进行因子分析，结果表明：绝缘聚合度、糠醛、CO_x被分为一类，代表绝缘老化因子：烃类、氢气、被分为一类，代表绝缘故障因子；因子分析结果与现场经验一致，相互印证，具有重要意义。
