Overload and High Voltage Tests of Witness Samples of 200m HTS Power Cable.

Abstract: 1.5/2 kA – 20kV has been developed and passed acceptance test in December 2009. This cable has superconducting shield and is made of DI-BSSCO™ HT-CA wires from Sumitomo Electric Company. The cable is installed at the experimental test facility to undergo extensive tests first, than it will be reinstalled to Moscow utility grid. As a part of the wide test program the fault current tests and high voltage tests were performed with pieces of the full length cable – so called witness samples. 44 kA fault current test has been performed as well as high voltage test for cable''s insulation. In this paper the results of fault current test and high voltage test are presented, discussed and analyzed. [Copyright &y& Elsevier]
