Abstract

The insulation characteristics parameters of high voltage cable are analyzed. Fuzzy comprehensive evaluation is introduced into multiparameter diagnosis of cable insulation. The fuzzy comprehensive evaluation model is established, and the grade of membership of insulation state is judged from multiple indicators. Consulting previous division standard of insulation state, the threshold of membership function is determined by relative variation of insulation parameters. This method simplified the diagnosis process with multiple parameters, and it is verified by the monitoring data of power cable.
