This work validates the partial discharge (PD) calibration procedure of PD analysers used for high voltage DC (HVDC) insulation diagnosis by means of an adjustable synthetic reference PD generator for HVDC cable systems and gas-insulated switchgear (GIS) setups. At the time when the project is started. the relation between PD pulse patterns and defects in internal insulation is not yet well known for HVDC stress. Although a qualification procedure using a PD waveform generator has been developed to study insulation under DC stress, the procedure needs to be extended to different PD patterns associated with each defect. Due to the vast variability of the phenomenon and acquisition techniques, large amounts of data are needed to identify PD patterns associated with the real defect. The project responds to the need of specific methods to recognize PD patterns, as well as PD calibrators to reproduce PD patterns applicable to measurements under DC stress. Moreover, the project tackles the lack of traceability of HVDC GIS partial discharge measurements due to the limited bandwidth of the sensors. These shortcomings are addressed by the development of novel calibration methodologies as well as appropriate high bandwidth sensors.
