Bragg Grating Sensor

This paper presents a method for the detection of transmission tower. It is a common phenomenon that high voltage and strong magnetic field exist in the environment of high voltage transmission tower. Compared with electronic sensor system, fiber Bragg grating sensing technology could resist harsh environment effectively. As a kind of passive devices, fiber Bragg grating tilt sensor can monitor the tilted state of high voltage tower easily. With the help of on-line monitoring system, we can effectively raise maintenance strategy for high voltage tower and analyze the variation trend of the tower. The system is convenient to repair and maintain the high voltage tower at the same time.
