Abstract

In this paper

the framework of system for CVT based on data mining technology is introduced.According to the secondary voltage data of CVT in the system

quasi real time on-line monitoring of capacitor breakdown can be achieved by the use of data mining technology which

compared to the traditional power off preventative test can find timely potential defect. The breakdown of CVT capacitance elements by using voltage variations is analyzed in theory. The effectiveness of the method is proved through an analysis of a typical case.Finally

two suggestions for CVT insulation monitoring are proposed.
