Abstract :
Partial discharge (PD) detection is a widely used tool for monitoring and diagnostics of high voltage gas insulated substations (GIS). Despite the fast growing demand of high voltage direct current (HVDC) interconnections, little research has been dedicated to PD monitoring systems for HVDC GIS. In this paper, conventional and unconventional PD detection systems are employed for the detection of three different defects common in GIS, and relevant PD analysis methods are presented. Finally, the analysis methods and detection systems are compared to point out their potential and limitations in monitoring PD in HVDC GIS.
