摘要

In order to measure propagaton velocities of the normal zone after a quench in a super-conducting wire or cable, voltage taps have usually been soldered on the sample conductor. However, the voltage taps may disturb the propagation process, becuse the joule heat generated in the normal region flows out through the taps. Furthermore, in the case of the multi-strand cable, the soldering may change the profile of the transport current because of formation of a short-circuit between strands. As a method of solving the above probelms, a noncontact measurement with a capactiance divider was proposed. The propagation velocity measured by the capacitance dividers was larger than that by the voltage taps. This fact suggests that the proposed method enables us to measure the propagation velocity without any thermal disturbance.
