Abstract
The results of the experimental studies of the short HTS cable models with the length of 1.2 and 2.4 meters under the DC and AC modes are presented. The electrical resistance of the soldered and the mechanical joints between the copper current-lead and the superconducting tape layer and between the superconducting tape layers were studied. The internal conductor of these models has three layers twisted with the left direction and with various values of the twist pitch. The influences of the total current ramp rate, the model length and the value of the electrical resistance between the layers on the current redistribution in the cable model were experimentally studied. The results are in a good agreement with the theoretical results predicted earlier. Some cryogenics test results at different temperatures in the range of 65 K-78 K are presented also.
