Failure and security risks of communication cable in electric power system caused by anomalous changing of strain is investigated. The current situation of the strain monitoring system for communication cable of electric power system is introduced as well. Besides, it presents the principle and features of measuring the strain by using fiber grating sensing technology. The new method that can be used in strain monitoring for key positions of communication cable in electric power system is put forward, and fiber grating sensor program is designed. Finally, several key technical problems in its practical application are analyzed in detail.
