Superconducting fault current limiters (SFCLs) are required to recover to the superconducting state as quickly as possible after limiting the fault current. It is important for the quick recovery to improve the cooling property of a superconducting tape. The boiling phenomena of liquid nitrogen on the surface of a superconducting tape have large influence on its cooling property. In this paper, we used GdBCO tapes for the resistive SFCL and investigated the effect of applying pressure for improvement of its recovery characteristics. In addition, we observed the difference of the boiling phenomena on the surface of GdBCO tapes between under pressurized condition and under ambient pressure by a high-speed video camera.
