Abstract

This paper presents a study of frequency dependence of the overcurrent characteristics of high-temperature superconducting (HTS) tape. Fault currents with different amplitudes and frequencies are applied to HTS tape, and the relationship between the overcurrent characteristics and current parameters are obtained after processing and analyzing the experimental results. In addition, a phase difference between the current peak and voltage peak is found in these experiments. Using both simulations and experiments, studies are carried out to find the reason for this phenomenon. Conclusions given in this paper provide useful information for optimizing the design of superconducting apparatus.
