Abstract
summarized and the experience gained about the PD behavior of some typical defects in
HVDC GIS and GIL are discussed. Some physical effects at different voltage levels are
shown and a method for the representation and characterization of the PD pulse
sequences is introduced. Special test cells with different types of defects such as a
protrusion, a floating electrode, a free moving particle and a void are used for the
investigations. The procedure for PD measurement at DC voltage is improved and PD
pulse sequences at different gas pressures and voltage levels were recorded. In a further
step the PD behavior up to the breakdown voltage was determined. The NoDi* pattern
was developed for the visualization and interpretation of the measured PD pulse
sequences. This pattern supports the visualization and the physical interpretation of the
pulse sequences and may allow the characterization of the typical defects in HVDC GIS
and GIL by a human expert.

N2 - In this paper the requirements on PD measurement systems for DC voltage aresummarized and the experience gained about the PD behavior of some typical defects inHVDC GIS and GIL are discussed. Some physical effects at different voltage levels areshown and a method for the representation and characterization of the PD pulsesequences is introduced. Special test cells with different types of defects such as aprotrusion, a floating electrode, a free moving particle and a void are used for theinvestigations. The procedure for PD measurement at DC voltage is improved and PDpulse sequences at different gas pressures and voltage levels were recorded. In a furtherstep the PD behavior up to the breakdown voltage was determined. The NoDi* patternwas developed for the visualization and interpretation of the measured PD pulsesequences. This pattern supports the visualization and the physical interpretation of thepulse sequences and may allow the characterization of the typical defects in HVDC GISand GIL by a human expert.
