Abstract : Distributed optical fiber temperature sensing is a newly developed technique for the measurement of spatial temperature distribu2 tion. It can be used to monitor temperature along an optical fiber of some kilometers . The optical fiber itself is both the sensing elements and the signal transmission medium. Because of its intrinsic advantages , this technique is especially suitable for the temperature monitoring of electrical power facilities . When combined with other fire protection techniques , distributed optical fiber temperature sensor system should be widely used in the state monitoring of electrical facilities in electrical power plants , substations and so forth.
Key words : fiber ; laser ; temperature monitoring ; electrical facilities
