N2 - Superconducting cables with critical currents in the range of 50 kA to 200 kA are presently under investigation in Twente. Therefore, a low-cost test facility has been developed in which the required current is generated inductively, allowing cables to be tested up to at least 200 kA. A superconducting transformer induces the current through the sample and provides the background magnetic field. The secondary part of the transformer consists of one turn of the test cable. A part of it can be varied in temperature by means of a heater. The data aquisition, analysis and storage is accomplished by means of a microcomputer system. So far, two cables having critical currents in the order of 100 kA have been successfully tested concerning their maximum current, stability and quench behaviour. The paper describes the test set-up and presents some first results.
