Description: International audience ; In this paper, we propose a new model taking into account local thermal effect on the cable. A thinner modelling combining the ABCD frequency method with a mesh description of the network is used to analyse the effect of a progressive temperature profile on the cable. Two cases were considered : a drastic drop and an important raise of the temperature. Numerical simulations and reflectometry experimental measurements were conducted to validate the new model. Great similarities were observed and reflectometry sensors showed that hot and cold spots can be detected and located.
