Transmission Line Monitoring

On-line monitoring of high voltage transmission lines can prevent or reduce the accidents of transmission reduced by icing,wave,breeze vibrations of electric wires and the dropping of electrical insulators.An on-line monitoring system of high voltage transmission lines based on optical fiber sensing technology is setted in this paper.Fiber optic signal demodulation instrument in the transformer substation receives the signal sent by the optical fiber Bragg grating sensors fitted on transmission lines and electric power towers,and then the signal was sent to the transmission line monitoring center by the power system network.Field hang net experiments shows that the system can monitor the high voltage transmission lines accurately for a long time.

The operation environment of the transmission line directly affects the operation safety of the transmission line. This article studied a FBG temperature and humidity sensor based on optical fiber sensing technology for transmission lines. Firstly, this paper studies the packaging method of the sensor, then designs the corresponding installation fixture, and gives its installation diagram. Finally, the performance of the FBG is tested in the experimental box and the national optoelectronic information product quality supervision and inspection center, and the test results show that the performance of the FBG temperature and humidity sensor is better.
