Quench detection method and apparatus of superconductive conductor
摘要
<p>When supplying electric power to a superconducting cable including a superconducting shield covering a superconductive conductor, a phase A of a current generated by a magnetic field leaking from the superconducting shield and a phase B of a current passing through the superconductive conductor are detected, and a phase difference between the phase A and the phase B is obtained so as to determine that a quench has occurred in the case where a difference between a reference phase difference and the obtained current phase difference exceeds a threshold.</p>
