Abstract

The pulse current detection method in GIS interval with cable outlet is analyzed

and the optimization method of the combination of UHF detection and pulse current detection is proposed. Using the pulse current method to assist the partial discharge location technology of UHF

further phase locating is performed on the three phase in one tank type GIS

the diagnostic accuracy of GIS device is improved.
