<p>A characteristic enclosure, configured to surround a linear conductor, includes at least one internal cavity for receiving at least one fiber optic sensor or current transformer sensor wound about the enclosure and giving a measurement of current. The cavity is closed except at openings of small size in the outer wall through which the sensors are inserted, or are removed to replace them, and through which they are connected to a measuring apparatus. The enclosure includes grooves arranged on its surface or in separate tubes for guiding and maintaining loops of the sensors. Advantageously, one of the walls of the enclosure extends the walls of the adjacent enclosures for a regular flow of current induced along the enclosure.</p> |
