Methods, device and installation for locating a defect in an electric link

A method for locating a defect in an electric link, comprising:

• measuring at least one part of components of an electromagnetic field in a vicinity of an estimated location of the defect at plural places along the link;
• deducing, via a processor, from the measuring an estimation of variation of at least the part of the components of the electromagnetic field along the electric link in a vicinity of the estimated location of the defect;
• and
• estimating, via the processor, a new location of the defect as a function of the estimated variation of at least the part of the components of the electromagnetic field.

A device for locating a defect in an electric link, comprising:

• a measuring device for measuring at least one part of components of an electromagnetic field in a vicinity of an estimated location of the defect at plural places along the link;
• and
• a processor which deduces from the measuring output from the measuring device an estimation of variation of at least the part of the components of the electromagnetic field along the electric link in a vicinity of the estimated location of the defect;
• and which estimates a new location of the defect as a function of the estimated variation of at least the part of the components of the electromagnetic field.
