    Abstract

    A high temperature superconductor (HTS) cable conductor (CC) with a critical current of 2.1 kA was tested over a range of short-circuit currents up to 20 kA. The duration of the short-circuit currents is 1 s. Between each short-circuit test the critical current of the HTS CC was measured in order to detect degradation due to the short-circuit current. During the over-current testing the current and voltage along the CC were measured as well as its temperature. Significant warming above the critical temperature occurs for short-circuit currents of 10 kA and above. No critical current degradation was found for currents up to 10 kA for 1 s, while some degradation (10%) was found for 20 kA. (C) 2002 Published by Elsevier Science B.V.
