NEWGEN aims to develop and demonstrate new insulation materials, cable manufacturing solutions, online condition monitoring technologies, and life and reliability modelling tools for next-generation of extruded high voltage direct current (HVDC) cables and cable systems. The project’s main objectives are to develop novel space charge mitigating additives and cable extrusion solutions for highly reliable polymeric HVDC cables; develop and demonstrate a novel online global monitoring system for pre-fault detection and health status evaluation of HVDC cable systems, and develop a comprehensive life and reliability model for HVDC cable systems.
