| Abstract: | In recent years,ultrahigh frequency-PD has developed rapidly.The technology of UltraHigh Frequency-PD was used to test more than 20 220 kV transformers.The test found that one of the transformers′PD anomaly,and combined with some special examination in power cut station.The test diagnosed the casing defect on the transformer and avoided the vicious accident. |
