Distributed optical fiber temperature sensing is a newly developed technique for the measurement of spatial temperature distribution. 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.
