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.
