Implementation of LiDAR and Photogrammetry in Right of Way Assessment for Improving Transmission Line Reliability

The transmission line is the backbone of electrical energy transfer. The reliability of the transmission line is influenced by the condition of the right-of-way path. Currently, the method used to assess the condition of the transmission tower and its ROW is done manually by ground patrol officers equipped with the Srintami application, which must be filled out along with photo evidence of the condition of each item of equipment being assessed. The level of accuracy achieved by using this method is highly dependent on the perceptions of officers and is prone to errors in providing information, so it will affect the results of the assessment and does not comprehensively describe the real conditions in the field. As the development of UAV technology is increasing rapidly, it is possible to apply the use of UAVs for mapping so that the problems that arise in the mapping of ground patrol officers, such as extreme terrain conditions, are no longer a problem. There are two methods of mapping UAVs based on the type of payload used. The first is photogrammetry, which utilizes the camera from the UAV, and the second is using the LiDAR sensor. In photogrammetry, the image results are then processed into a series of photos that are assembled into a 2D map that describes the actual conditions of the transmission line, while in LiDAR, the results of image processing can be in the form of a 3D map, which can directly analyze the distance between the stand and the tower. By combining these two pieces of information, the accuracy of the transmission line conditions becomes more accurate, so that more careful planning can be carried out regarding maintenance that can maintain the reliability of the transmission line.
