Abstract
In this paper
the main function of capacitor voltage transformer(CVT)and several kinds of CVTs with special structures encountered in the operation period are briefly described.Special test methods are adopted for different CVTs
several modification methods are proposed based on fault site analysis of the most common kind of CVT to provide reference for the maintenance people.
