Research on Partial Discharge Location Method of DC Wall Bushing Based on Partial Discharge Transfer Ratio

In order to solve the problem of abnormal result in partial discharge test of DC wall bushing, a partial discharge location method based on partial discharge transfer ratio is proposed in this paper. The mechanism of the location method of partial discharge is described first, and the partial discharge test of DC wall bushing is carried out in engineering application. The test results verify the effectiveness of the location method based on partial discharge transfer ratio.
