WANG Jian-jian, LI Yong-qian. Progress on Distributed Optical Fiber Sensing Technology in OPGW Monitoring[J]. 2018,(3):25-27. DOI: 10.13756/j.gtxyj.2018.03.007.
Optical Fiber Composite Overhead Ground Wire(OPGW)is a kind of widely used power cables
which has the function of overhead transmission line and optical fiber communication carrier.OPGW works outdoors for a long time
which will be affected by environmental factors and human factors.Monitoring and maintenance of OPGW is an important guarantee for the normal operation of the power system.In this paper
we first introduce the current development of the distributed optical fiber sensing technology based on Brillouin scattering in OPGW monitoring.Then the existing problems and future application prospect are also discussed.
