In order to overcome the drawbacks of the existing icing-monitoring systems, such as the requirement for field power, the sensitivity to electromagnetic interference(EMI), the unavailability of distribution measurement and a short lifespan, an on-line monitoring method for transmission line icing based on distributed optical fiber sensing technology was constructed. Through the selection of optical fiber composite ground wire tension changes value as the icing of the impact factor, regres-sion analysis, pushed to the icing regression analysis model to realize the monitoring of optical fiber composite ground wire is covered with ice.
