Editorial - Special Issue on Worshop on HVDC cables and accessories

Following the proposal by the Organizing Committee of the 2016 CEIDP, a TC workshop on HVDC extruded cable systems was held at the meeting on Sunday, October 16, 2016, in Toronto, Ontario, Canada. This first workshop was intended to provide an overview of some of the major issues faced by HVDC extruded cable systems. Seven people gave presentations on the following topics: • basics about HVDC cable transmission (G. Mazzanti); • design of HVDC extruded cables and accessories (F. Mauseth); • traditional (C. Reed) and innovative (T. Andritsch) extruded insulating materials for HVDC cables; • space-charge measurements on HVDC extruded cables with PEA (T.Tanaka) and TSM (J. Castellon); • contents and development of the IEEE 1732 Standard (G. Mazzanti); • life modeling of HVDC extruded cables (G. Mazzanti); • life exponent in the V-t characteristic for HVDC extruded cables (K. Wu). The workshop was a huge success, with 27 participants representing a good cross section of expertise to learn from other researchers in the field. As suggested by Ed Cherney, co-editor-in-chief of the Magazine, the presentations were compiled into articles for this issue.
