“…In 1995-1996, a test facility for 10 kA high-temperature superconducting current leads was built at CRPP [3]. The test station included a 12 kA DC power supply, a medium size cryostat connected to the main CRPP helium refrigerator by a supercritical helium transfer line and a 96 channels data acquisition system.…”

A new test facility, dedicated to the measurement of contact resistance distribution in full-size conductor termination, has been designed and manufactured at CRPP Fusion Technology in Villigen, Switzerland. The facility will be used to characterize and qualify the ITER joints (both prototype and industrial). The basic components of the new facility are: a medium size, liquid helium cryostat to host the termination sample, a cryogenic, parallel resistor array for providing balanced current injection in up to 100 channels, a 10 kA DC power supply (100 channels of each 100 A), a pair of conventional current leads rated at 10 kA and a data acquisition system with 200 analogue input channels (100 voltage and 100 current readouts). As opposed to the earlier attempts where the contact resistance was measured under an unbalanced current distribution (only one strand was connected to the current source) in the new facility the contact resistance is measured under imposed balanced current distribution among all current carrying elements and the voltage drops are sensed simultaneously.

Abstrrrct-In the frame of the European Fusion TechnologyProgramme, the Forschungszentrum Karlsruhe and the CRPP Villigen have been developing a 60 kA current lead for the ITER TF coils using High Temperature Superconductor (HTS). In part 3 of the task, a 20 kA HTS current lead was assembled using two 81-2223 modules manufactured in industry. The performance test was carried out at NIFS, Japan, as part of the LIME project. The test covers the electrical and thermal behaviour in both steady state and transient operation. Current sharing was observed between two modules and the quench current o f the current lead was evaluated about 30 kA at the design conditions. The results suggest that it is possible to satisfy all requirements needed for the leads o f the I T E R T F coils.Index Terms-High temperature superconductor, current leads.
