| Abstract: | The progress of ultrahigh frequency (UHF)based on-line monitoring of gas insulated switchgear (GIS) in recent years is summarized, including the research results in the UHF transducers, the propagation characteristics of UHF electromagnetic wave in GIS, the recognition and location of partial discharge source and so on. The problems existing in the UHF based on-line monitoring system and its application, such as the selection of detecting frequency band, etc. The direction in the future research on UHF based partial dischargemonitoring is looked ahead and it is pointed out that the easy and fast partial discharge location by new types of transducers is still the focal point of the research. |
