Abstract

In this paper

the abnormalities of a certain 220 kV busbar capacitor voltage transformer during operation are described. The disassembly procedure of the voltage transformer is introduced

and the faulty point is found out based on the abnormalities. The reason of voltage rise at its secondary side is analyzed and the countermeasures on preventing such fault is raised

which can provide reference to analyzing and treating the similar fault.
