At present, China has built six major inter-provincial power grids, namely the power grids of the South, Northwest, East China, Central China, North China and Northeast China. And AC and DC transmission lines of 500kV and above are mainly used. During the construction and expansion, to traverse various complex terrains is a known difficulty to face in both the early engineering and the later maintenance. In particular, how to solve the accuracy and efficiency of power line inspection has always been a major problem that plagues the power industry.
On 18th August 2016, China Southern Power Grid Super High Voltage Company successfully completed their first power inspection using SureStar's E+RA LiDAR system. This flight was supported with kind effort by Zhuhai Helicopter Branch of China Southern Airlines Co. Ltd.
E+AP LiDAR Transmission Line Inspection System, with a build-in wide-angle digital combination camera system and environmental sensors, can obtain high-precision ture color point cloud data of the transmission lines and anything within the corridor and then form a comprehensive database for digitization management and further maintenance.
