Current transfer length in 2G HTS tape considering multi-layers
Abstract
A novel numerical method of calculating the current transfer length (CTL) from several matrices to superconducting region has been proposed in this paper, there are two ways to calculate the CTL corresponding to two criteria of CTL: E-based criterion and I-based criterion, and the relationship between these criteria have been given again. The method of calculating the CTL from several matrices to superconducting region has high accuracy compared with the method introduced by Stenvall, and simulation and experiments of measuring the CTL have been carried out to compare with the ones calculated by the numerical method. The results show that the novel numerical method has high accuracy in calculating the CTL of superconducting tape and is useful for generalizing to calculate the CTL of superconducting cable.
