Fiber optic temperature sensors are excellent candidates for monitoring the temperature along the stator windings of a large electric power generator. Unlike thermocouple thermometers, they are immune to the effects of strong magnetic fields which are present in all power generators. Several different point and line sensors have been evaluated in their ability to resolve temperature and temperature distribution (respectively), as well as their compatibility with the generator environment. The sensor must function inside the generator for long periods of time (up to 25 years) without benefit of recalibration. This constraint has required us to devise methods by which the sensor may remain permanently calibrated. In almost all cases, it is necessary to measure a natural characteristic of a device which is temperature sensitive in order to achieve permanent calibration. This will enable the device to function despite the varying characteristics of the source and detector equipment.
