The reliability of a current transformer affects the safe operation of a power grid
which highly depends on its dielectric performance.Partial discharge detection is a very important method for the evaluation of dielectric performance of a current transformer.In this paper
the pulse current method for detecting partial discharge(PD) is analyzed
and the PD test circuit was discussed.Because PD detection is easily disturbed
different kinds of interference signals are detected for investigating their characteristics
finding out the sources of the signals
and hence taking special measures to suppress the interference signals.
