Paper Abstract

Distributed temperature sensing (DTS) of long distance power cables is shown to provide valuable information for cable design optimisation and proper operation of wind farms. The long range sensing is enabled by using the Raman-OFDR (optical frequency domain reflectometry) technology in single-mode fibres. Raman-OFDR uses a modulated continuous wave laser for detection. The low peak power minimizes stimulated Raman-scattering in single-mode fibres making accurate temperature sensing over long distances feasible.
