       During the operation of power transmission lines, in addition to being prone to sudden faults such as lightning strikes, floating objects, and wind deviations, there are also a large number of potential preventable defects, such as insulator degradation, hardware breakage and detachment, insulator contamination, excessive vegetation, icing, and more. Failure to address these hazards promptly can pose serious safety risks to the stability of the power grid. Therefore, prevention before faults and rapid recovery after faults are crucial means to enhance the reliability of line operation.

Monitoring devices are distributedly installed on the conductors of transmission lines to monitor the operation of the lines. The data center conducts comprehensive analysis to automatically monitor and warn of potential hazards on the line and to diagnose faults quickly and accurately. Warning messages are sent out via both web and SMS.
