“…The critical current (I c ) measurements were conducted for each phase conductor at an average cable temperature of 73 K. The critical currents of all phases were 2300 A, respectively, when the current was defined as 1 lV/cm, for all three phases. The measured I c s matched the values expected from the results of a sample test at 77 K of 1800 A [4]. The heat invasion into the cable system in no-load condition was measured.…”

The counterflow cooling configuration is a compact, efficient, and relatively low cost thermal management approach for long-length HTS cable systems. In the counter-flow cooling configuration the coolant flow, typically liquid nitrogen, is initially supplied through the center of the cable turning around at the far end of the cable and returning through the annular space between the cable and the inner cryostat wall, using a single cryostat. The temperature distributions along the cable and the nitrogen flow streams are extremely difficult to measure in an operating HTS cable because of the issues associated with installing thermometers on high voltage components. A 5-meter long test loop has been built that simulates a counter-flow cooled, HTS cable using a heated metal tube to simulate the cable. The test loop contains calibrated thermometers to measure the temperature distribution along the tube and the return liquid nitrogen stream. Measured temperature distributions in the return flow stream and along the tube wall for varying flow rates and heating conditions to simulate a HTS cable are presented and discussed.

“…Because of its large capacity and compactness compared with conventional power cables, the HTS (High Temperature Superconducting) power cables are being developed by LIPA (Long Island Power Authority), AEP Ohio (American Electric Power) and Albany projects [1][2][3]. Several HTS power devices have already been connected to the real utility grid.…”
