Calorimetric measurements of losses in HTS cables

A calorimetric test rig is used to investigate various loss components in a 10 m long superconducting cable model. A calorimetric technique, based on thermocouple measurements, Is used to me asure the losses of the 10 m long superconducting cable model. The current dependent losses;Ire also measured electrically and compared with the losse s obtained with the calorimetric method. The results obtained by the two me thods are consistent. Based on an I-2 (current) fitting procedure, the loss,:caused by the eddy c urrent generated in the stainless steel cryostat housing, and the hysteresi s loss generated in the conductor can be separated. From this result, it ap pears that the two contributions are roughly equal in size.
