Experiences with cable faults located at metallic screen connections [PDF]

open access: hybridCIRED - Open Access Proceedings Journal, 2017
Overheating of metallic ground screen connections at accessories of single core cables are the root cause of severe insulation failures in the distribution network. The overheating is due to a high transition resistance of the connections combined with high induced currents in the ground screens during operation.
