| Abstract: | In this paper, the operation principle and the test connecting of frequency conversion power supply are introduced in detail. Some notable problems in field test are analyzed, and the concrete solutions are also put forward according to field practicing. Based on this method, the partial discharge test for the first domestic transformer, three phase in one tank, 500 kV 720 MV·A, is accomplished successfully. This is also a beneficial attempt about partial discharge field measurement of high voltage, huge capacity transformer. |
