Experimental studies demonstrate critical current evaluation in HTS DC cables, suggesting efficient energy transmission methods.
Key Points
This research aims to evaluate the critical current capacity of HTS (high-temperature superconducting) cables combined with LH2 (liquid hydrogen) for efficient energy transmission.
Evaluated critical current for each HTS tape based on voltage drops across the cable
Measured combined energy transmission capability of cables using 10 kA @ 25 K
Utilized ramping current methods to test cable functions
Conducted tests on multiple sample configurations (Samples A, B, C)
Sample A showed a high range of critical current for HTS tape but lower for the cable
Samples B and C demonstrated higher critical cable current despite lower HTS tape currents
Indications suggest improved efficiency in combining electrical and chemical energy transmission
