| Abstract: | The relative theory of the safety and efficiency as well as experiment are presented for the high-rated current lead design. The experiment results indicate the safety property is associated to current density of the resistive heat exchanger (HEX) and temperature margin of the HTS module. The HEX cooling mass flow rate depends on the HEX efficiency, which relates to heat transfer area and coefficient etc. |
