Abstract

The Albany Cable Project team (BOC, National Grid, Sumitomo Electric, SuperPower) have built and tested a 350-m long HTS cable and cryogenic system rated at 48 MVA (800 A_rms, 34.5-kV). The cable system included the world´s first demonstration of an HTS cable-to-cable joint (or splice) as well as some novel design aspects in both the cryogenic refrigeration system and the terminations. The cable was installed and began operation in July 2006. This paper will summarize the testing and operational aspects of the HTS cable system and its integration into the existing national grid 34.5-kV network.
