| Abstract: | For the transition resistance broken problem in actual operation, we describe the composition and working principle of tap changer. Compared with previous research papers, AC detection method is proposed.AC test device through several tests, test waveforms compared with current law has more advantages. AC method to test the transition resistance breaking wave of tap changer has a unique analyzing result and facilitate the analysis, which greatly improves the accuracy of fault diagnosis. It will have a great value in practice. |
