Abstract :
This paper describes the industrial prototype of an eight channel fiber-optic temperature sensor network, based on spectral modulation encoding techniques, and devoted to the thermal monitoring of the stator of 900 MW turbogenerators. Results of the qualification tests applied to this industrial prototype are provided as well as the description of its settlement in the nuclear power plan of TRICASTIN in France. Conclusions are drawn from the first six months of continuous operation
