TL;DR: In this paper, a method to measure short cables has been developed and is being improved, but only those of lengths from 1 m to 100 m. The method needed further improvement in order to make loss measurements of the BNL 138 kV, 4 kA, 100 m long superconducting cable now under construction.
Abstract: Loss measurement of superconducting cables are addressed, but only those of lengths from 1 m to 100 m. A method to measure short cables has been developed and is being improved. The method needed further improvement in order to make loss measurements of the BNL 138 kV, 4 kA, 100 m long superconducting cable now under construction. The cable system consists of two coaxial cables connected in a circular loop so that voltage and induced current can be applied simultaneously. During the ac loss measurements it will be run without high voltage. The short cable loss measurement and the 100 m cable system loss measurement circuits are illustrated. The new measurement method appears to be suitable for the BNL superconducting 100 m cable. In the case of a long cable the accuracy will be higher because of larger absolute losses, corresponding to a higher signal-to-noise ratio.
