This issue of the Magazine presents articles related to cable diagnostics and technology. Two of them, written by authors from Canada and Australia, summarize experiences and research activities on the use of dielectric response spectroscopy for diagnoses of insulation condition in medium voltage cables. The third article presents work performed in the USA on development of superconducting gas insulated cable system for power transmission at voltage level above 10 kV. Finally, the fourth article, from Norway, raises the importance of mesoscale material effect on the performance of cable joints.
