The study to be undertaken by the Collaborator, University of Strathclyde will consist initially of a review of current state of the art with respect to partial discharge monitoring on HVAC as well as HVDC cable systems.
From the gaps in the knowledge identified through the review, a systematic and logical experimental work plan will be developed to understand partial discharges in HVDC cable systems. The work plan will be based on laboratory experimentation as well as computer simulation (where appropriate) to allow a better understanding of how partial discharges are generated in a HVDC cable system and the mechanism responsible.
To understand the degradation characteristic of cable insulation when subjected to HVDC.
The generation of new knowledge on the degradation characteristic of cable insulation when subjected to HVDC.
