Research on dehumidification of 1 000 kV GIS current transformer(CT) is important.The purpose of dehumidification of CT is to ensure its insulation performance in operation.Because GIS/HGIS are mostly adopted in structure of UHV substations and CT in GIS/HGIS is not easy to be disassembly
traditional dehumidification method of CT is not applicable.In order to find a compatible and a suitable dehumidification program of UHV CT and considering of special structure of CT in GIS/HGIS
this paper presents a solution of dehumidification through heating CT′s windings.The result shows that it is feasible to UHV CT.
