Quench and recovery characteristics of HTS film after fault current
고온초전도체 박막의 퀜치/회복 특성
Abstract
Quench and recovery process of high-temperature -superconductor (HTS) film deposited on the sapphire substrate is studied numerically. The quench is developed by fault current and the superconductivity is recovered by convection of heat into coolant. After the fault current, the HTS film experiences the quench state, current sharing state, and finally recovers the superconductivity. Numerical results of this study are compared to the previous experimental results, and shows that this numerical work can explain the mechanism of quench/recovery characteristics of HTS film.
