Strands inside a multistage Cable-in-Conduit Conductor (CICC) are characterized by limited electrical contacts amongst themselves and can often be described in terms of distributed constant circuit or as a lumped electrical circuit. Twisting stage-wise impedance-frequency characteristics nave been measured on short samples of SST-1 CICC both at room temperature and at liquid Nitrogen temperature from which the transient coupling currents arising from the uncompensated flux has been estimated. From these experimental results, the current transfer performance amongst the twisted strands within the CICC has been predicted for typical tokamak start-up scenarios. These electrical characteristics have been compared with those obtained from solder filled SST-1 joints and termination samples as they are very integral to the overall magnet performance. The electrical circuit characteristics trends are expected to remain same at the operating liquid He temperature also.
