Abstract

This paper deals with characteristics of a High-Tc superconductor (HTS) persistent current switch (PCS) system considering the n-value. I also present its operational characteristics through experiments. A HTS PCS system mainly consists of a PCS, a HTS magnet load, and a magnet power supply (MPS). The HTS magnet load was made-up of two double pancake coils in series. In order to measure the persistent current with respect to the magnet flux changes, a hall sensor was installed at the center of the magnet load. In the experiments, the initial current dropped rapidly in the persistent current mode. In order to analyze current decay, we introduced a new electrical equivalent model considering the n-value. Experimental results of the HTS PCS system have been compared with the theoretical results. It has been concluded that the characteristics of initial current decay were mainly determined by the voltages generated in the pancake load due to n-value and joint resistance.
