La présente invention permet le placement d'un ou de plusieurs des capteurs dans différentes parties du câble ou permet le placement d'un ou de plusieurs capteurs le long d'une section de câble. La présente invention permet l'utilisation desdits capteurs pour mesurer la déformation, la température, la pression ou d'autres caractéristiques physiques. La présente invention concerne également des procédés d'utilisation desdits dispositifs dans un réseau électrique faisant appel à des câbles composites.
