Problems solved by technology

This operation is very lengthy and risky, as the fiber can be damaged during the winding operation or during the normal assembly and setting of the electromagnetic induction device itself
Additionally, it is difficult or virtually impossible to measure the temperature inside the conductors forming the winding or in the internal components of the winding

Abstract

A continuously transposed cable CTC (1), extending according to a longitudinal development direction (L) and having two opposite longitudinal ends (2, 3), comprises a plurality of strands (4) arrangedso to form at least a first (5) and a second (6) adjacent stacks, each extending along the longitudinal development direction (L), wherein said at least first (5) and second (6) stacks form a longitudinal interface (16) therebetween. The CTC cable (1) further comprises one or more optical fibers (12) positioned at the interface (16) between the first (5) and the second (6) stacks. A winding of anelectromagnetic induction device, such as a transformer, can be obtained by winding said CTC cable (1).

Description

technical field [0001] The present invention relates to a cable, in particular to a continuously transposed cable (CTC) with integrated sensing means, especially for measuring temperature and / or vibrations. The conductor according to the invention is especially intended for use in forming windings of electromagnetic induction devices such as transformers. Background technique [0002] Electromagnetic induction devices, such as transformers, are used in power systems for voltage level control. In particular, a transformer is an electromagnetic induction device that is used to step up and down voltage in a power system in order to generate, transmit and utilize electricity. Typically, a transformer comprises windings and a core made of, for example, laminated iron. [0003] In electromagnetic induction installations, the temperature of the windings should be monitored in order to detect possible problems, to plan maintenance or to determine whether certain components are agi...
