Title (EN) SELF-MONITORING SUPERCONDUCTING CABLES HAVING INTEGRATED OPTICAL FIBERS
(FR) CÂBLES SUPRACONDUCTEURS À AUTO-SURVEILLANCE AYANT DES FIBRES OPTIQUES INTÉGRÉES
Abstract:
(EN) Disclosed are various embodiments for a self-monitoring conducting device that responds to strain and temperature changes. In one example, a self-monitoring conducting device comprises a superconducting cable having a core and one or more layers of high-temperature superconductor (HTS) tape architecture surrounding the core. The self-monitoring conducting device further includes optical fibers integrated within the superconducting cable. The optical fibers can monitor a state of the superconducting cable along a length of the superconducting cable.
(FR) L'invention concerne divers modes de réalisation pour un dispositif conducteur à auto-surveillance qui répond à des changements de contrainte et de température. Dans un exemple, un dispositif conducteur à auto-surveillance comprend un câble supraconducteur ayant un noyau et une ou plusieurs couches d'une architecture de bande supraconductrice à haute température (HTS) entourant le noyau. Le dispositif conducteur à auto-surveillance comprend en outre des fibres optiques intégrées dans le câble supraconducteur. Les fibres optiques peuvent surveiller un état du câble supraconducteur le long d'une longueur du câble supraconducteur.
