In this paper,comparative research on the UHF method and the pulse current method for partial discharge measurement of 1 100kV GIS was carried out, and the discharge was generated by artificial defect models set in the tank. The relationship of test results contained by the two means above was determined. Advices for test of partial discharge measurement devices is given,which can provide technical reference to GIS partial discharge monitoring system. The achievements above can be applied to the UHV engineering in China, which may reduce the economic losses caused by GIS failures and on-site restoration.
