<P>PROBLEM TO BE SOLVED: To provide a superconducting device operation method and a superconducting device. <P>SOLUTION: A standard measurement area and a first measurement area are partitioned on the surface of a stabilization layer, and voltages of these areas are measured. Regarding these voltages, the minimum voltage detectable by a voltmeter is set to Vd. An oxide superconductor is cooled to the critical temperature or lower, and power is supplied from a power supply. The temperature and the temperature rise rate of the oxide superconductor at a position in time and space where the minimum voltage Vd is detected are represented by Ta and dTa/dt, respectively. The interruption response time which a switching device may take to interrupt a current from the power supply is represented by Td. The temperature of the oxide superconductor at the point in time of the current interruption is set to Ts. Then, the power supply is disconnected to satisfy a condition of Ts=Ta+dTa/dt×Td≤500K(K: absolute temperature). <P>COPYRIGHT: (C)2012,JPO&INPIT |
