Abstract

AC loss is an important issue in the design of high-T$_{c}$ superconducting Power cables. The cables consists of a number of Bi-2223 tapes wound on a former. In such cables tapes have different critical current characteristics intrinsically. And they are electrically connected to each other and current leads by soldering. These make loss measurements considerably complex, especially for short samples of laboratory size. Special cautions are required in the positioning of voltage leads for measuring the true loss voltage. In this work the at losses in a single layer model cable have been experimentally investigated for different contacts and arrangements of voltage leads. The results show that the losses are not dependent on both arrangements and contact positions of the voltage leads. This implies that loss flux is only in a cylindrical conductor section. The measured losses also agree well with those based on a monoblock model and are independent of frequencies. This means that the measured AC loss of the model cable is purely hysteretic in nature.e.
