【Abstract】　Optical fiber temperature sensor system is a newly developed technique for the mea2surement of spatial temperature dist ribution. It can be used to monitor temperature along an opti2 cal fiber of some kilometers. The optical fiber it self is both the sensing element s and the signal t ransmission medium. Because of it s int rinsic advantages , this technique is especially suitable for the temperature monitoring of elect rical power facilities. When combined with other fire protec2 tion techniques , dist ributed optical fiber temperature sensor system will be widely used in the state monitoring of elect rical facilities in elect rical power plant , substations and so forth.
