TL;DR: In this article, the authors describe the methods and results of the DC critical current and AC loss measurements of the superconducting cable core, which are used as a reference added on the IEC cable qualification standards for the 3rd party inspection test.
Abstract: We had designed and manufactured a 22.9 kV/50 MVA class HTS (high temperature superconducting) power cable in cooperation with LS Cable Ltd. The HTS cable system was installed on the testing site of KEPCO (Korea Electric Power Corporation) in Kochang, Korea on March 2007. Some measurements which are related with electrical insulation characteristics such as partial discharge (PD) and tan δ were performed in accordance with the general guidance prescribed in IEC cable qualification standards. And also we measured the DC critical current of the HTS cable core and the AC loss for various transport currents and some temperature levels. These two testing results will be used just as a reference added on the IEC cable qualification standards for the 3rd party inspection test. In this paper, we describe the methods and results of the DC critical current and AC loss measurements of the superconducting cable core.
