Study On Transmission Lines On-line Monitoring Technique

The generalization and application of transmission lines on-line monitoring technique are the inevitable requests to make power system work well and to increase the transmission capability of power system. In the meanwhile, the lack of human resources become more and more obvious because of the great development of electricity grid system. It is hard to find out most of the equipments safty problems to the naked eye, such as too high of the wire working temperature, changes of the wire sag, windage yaw discharge, aeolian vibration, inclination of inclination, and so on. To solve the problems above, the technical ways must be innovated. Some correlative sensors are fixed on power transmission lines, the damage to the power transmission lines and equipments can be detected timely by the means of on-line monitoring technique, the state of the equipments can be estimated accordingly,so the existing limited human resources and outfits can be used to fix the equipments which need repair. On-line monitoring technique proves a reliable guarantee in technique and management to make sure that, the equipments can be operated safely, steadily, long-period and efficiently.
