| Abstract: | A novel type of optical sensor is designed, whose principle is based on resonance of optical fiber. This sensor can detect the vibration of 10-5 m level. It isn’t subject to strong electromagnetic field and temperature variation. It’s suitable for real time supervision on stator end-winding of generator(300 MW). With this novel sensor, the life of normal generators can be well elongated. |
