Research on Identification of Geological Hazards in Wide Area Transmission Lines Using Time-series InSAR.

High-voltage power transmission equipment is often deployed in inaccessible wild areas covered with vegetation and complex terrain conditions. Geological disasters often occur in these areas where line corridors and towers locations need to be paid attention to. Therefore, it is of great practical significance to ensure the safe and stable operation of power transmission equipment and facilities. Aiming at the high-voltage transmission line network widely erected within the jurisdiction of Kunming, this paper uses the time-series InSAR technique to identify the early geological hazards along the corridor. This technique could provide guarantee for the safe and stable operation of the transmission line.
