摘要

电力变压器绝缘的状态监测应集中在预测在水分、油副产品、污染颗粒、纸绝缘老化和局部放电活动的影响下介电安全裕度的大幅下降。结合实际经验，探讨了电力变压器绝缘功能失效模型及可能有效的绝缘状态评估方法。

Effective methods of assessment of insulation system conditions in power transformers: a view based on practical experience

Condition-based monitoring of power transformer insulation should center on the prediction of a substantial drop in the dielectric safety margin under the impact of moisture, oil by-products, contaminating particles, paper insulation aging and partial discharge activity. A functional failure model of power transformer insulation and possible effective methods of the insulation condition assessment are discussed based on practical experience.
