What is Distributed Temperature Sensing (DTS)?


#1

Distributed Temperature Sensing (DTS)

Distributed Temperature Sensing (DTS) is a branch of condition monitoring whereby the temperature of an optical fibre, at any point long its route, can be determined with a high degree of accuracy.

Increasingly, high and extra high voltage underground cables are being manufactured with an optical fibre incorporated in such a way that it is either adjacent to the conductor insulation or as close as is practical.

A profile of the conductor/s temperature can then be extrapolated from the fibre temperature and this temperature can then be used as a basis for a system rating calculation.
