Measurement of wind speed is an essential part of overhead transmission line monitoring. To overcome the drawbacks of the existing anemometer, such as the requirement on field power, the sensitivity to electromagnetic interference, and the unavailability of real-time measurement, a novel anemometer is developed on the basis of the fiber Bragg grating (FBG) sensing technique. In the anemometer, a beam...
Traditional tension sensors used in ice monitoring on transmission lines are easily disturbed by the strong electromagnetic field. In this paper, a novel optical measuring system in the basis of Fiber Bragg Grating(FBG) sensing technology is proposed. The FBG tension sensor is designed based on shear beam, and its sensitivity is then analyzed. The results of tension experiment indicate the sensor...
