Abstract

The measurement of current sharing temperature of Cable in Conduit Conductors is the main test for the acceptance of superconducting cables for the ITER Project. This temperature is defined as the one at which the average electric field along the cable reaches a critical value of 10 microV/m. Due to the complexity of the measurement, the evaluation of Tcs from the experimental results is not straightforward. Different techniques of elaboration of the raw experimental data can result in rather different estimations of Tcs. The aim of this work is to elaborate a standardized procedure of data treatment to be applied to all measurements. To this purpose, the assessment of the impact of the different measurement methodologies and data treatment techniques applied in the procedure is very important. A sensitivity analysis is therefore presented, to evaluate the influence on the final evaluation of of the main parameters and methodologies involved in the proposed procedure.
