Classification evaluation of transformer insulation condition based on matter-element theory

YANG Lixi,YU Fawei,BAO Yi(Electrical Engineering College,Zhengzhou University,Zhengzhou 450001,China)  
In order to improve the self-healing ability of power network and realize the online monitoring or pre-assessment of the main electrical equipment,a classification evaluation model based on matter-element theory is proposed for the insulation condition of transformer.The state variables affecting the insulation condition of transformer are analyzed and a hierarchical condition evaluation index system is built.The state variable is represented by matter-element and the matter-element differential square transformation is used to quantify the evaluation index.The matter-element of expert validity is introduced to treat the weights more objectively.With Euclid approach degree concept,the pattern recognition or classification of transformer insulation condition is achieved.Example analysis shows the assessment is more objective and practical.
