Recently gas insulated switchgears (GIS) have been applied to many substations because the large capacity, the high reliability and the small size of power equipments are required. If a. break-down happens in GIS, it needs a lot of man's power and a long time to restore. So, the diagnosis of GIS to find partial discharge on the early stage before a break-down is necessary. In this paper, for realizing it, an identification for sources of partial discharge using the time domain wave shapes by the ultra high frequency method is studied. Our experiments are carried out using four kinds of artificial sources such as (1) needle on central conductor, (2) floating needle, (3) needle on insulating spacer and (4) free metal particles in a model GIS (300 kV). It is pointed out that an important relation between the peak value of rectified waves and the half-width depends on the source. As a result, the sources of partial discharge can be identified more clearly by the combination of both the relation and the conventional phase characteristics.
