Superconducting cables based on high temperature superconductors (HTS) are necessary for applications requiring large currents and low inductance, such as compact fusion reactors. In this paper, we report the proof-of-concept of a SMART Conductor on Round Core (CORC) wire realized via integration of optical fibers into the copper core. A SMART CORC wire with integrated optical fibers was manufactured and its capabilities have been experimentally demonstrated. Results show that by interrogating the optical fibers via Rayleigh backscattering, a Spectral Shift signal as a function of time and position along the cable can be used to detect and locate hot-spots that are developed within the wire or its terminations. It has been found that highly localized current injection into the terminations could initiate hot-spots within the cable at locations where current redistribution between tapes occur. This effect is virtually eliminated when adequate current connections are used that inject current evenly along the cable terminations. Normal zone propagation velocities have been calculated as a function of time using Spectral Shift data for a heater-induced quench as well as a quench induced by overcurrent. In both cases the normal zone propagation velocity was about 6 cm s⁻¹, but in the heater-induced experiment it was preceded by 500 ms of slower propagation at 2.5 cm s⁻¹.

基于高温超导体 (HTS) 的超导电缆对于需要大电流和低电感的应用（例如紧凑型聚变反应堆）是必需的。在本文中，我们报告了圆芯智能导体 (CORC) 的概念验证) 导线通过将光纤集成到铜芯中来实现。一个聪明的CORC制造了集成光纤的电线，并通过实验证明了它的能力。结果表明，通过瑞利反向散射询问光纤，作为时间和沿电缆位置的函数的光谱位移信号可用于检测和定位在电线或其终端内产生的热点。已经发现，高度局部化的电流注入终端可能会在电缆内在磁带之间发生电流重新分布的位置引发热点。当使用足够的电流连接沿电缆终端均匀注入电流时，这种影响几乎可以消除。使用光谱位移数据计算了正常区域传播速度作为时间的函数，用于加热器引起的失超以及由过电流引起的失超。在这两种情况下，正常区域传播速度约为 6 cm s^-1，但在加热器诱导的实验中，它之前以 2.5 cm s ^-1的速度进行了 500 ms 的较慢传播。
