| Abstract: | This paper introduces the on-site PD testing method by using variable frequency power,analyzes the interferences on test result,and summarizes the ways for suppressing the interferences.Through two on-site PD tests,the procedure of suppressing the interferences is introduced.Moreover,the influences of bushing tap with imperfect earth on on-site PD test of transformers are analyzed,and a method to suppress these interferences is suggested. |
