摘要: Several AC power applications of YBCO-coated conductors (CCs) involve superconducting tapes wound in coils. In such a configuration the tape is arranged as closely packed turns, which strongly interact due to generated magnetic field. This has strong influence on losses, are different from those an isolated tape, and need be precisely quantified order predict reduce refrigeration requirements applications. this paper we experimentally evaluate transport losses pancake coil composed 25 turns tape. We describe detail measuring technique utilized, pointing out issues kind measurement. also present preliminary results loss computation by finite-element modelling.
