The field PD test of converter transformer is more difficult than that the test of common AC transformer. The most important difference is that the interference source in converter station is more complex. This paper measured the interference signals of the converter transformer field PD test in several converter stations, analyzed the characteristics of various typical interference, formulated the targeted interference suppression measures, simulation tests are carried out to verify the effectiveness of the suppression measures. Finally, the field application shows that the interference suppression measures proposed in this paper can effectively improve the efficiency and accuracy of field PD test of converter transformer.
