Drone solutions automate inspections and provide accurate data on all parts of the grid, enabling timely repairs, removing risk of accidents, and reducing downtime.
DAI-ATLAS
Satellite, IoT sensors, and DAI-UAV VTOL sorties converge in a live map — volumetrics, risk, change, and projection before the rest of the market.
Drones are an attractive alternative for power line inspection. Here are the potential benefits of using a drone:
Traditional power line inspections require inspectors to stand on scaffolding and cranes and use rope access to climb on poles. Drone surveying for the power grid eliminates the need to put people in harm's way, and line workers can safely remain on the ground while the drone operator assesses the line.
Traditional methods require a team of experienced linemen to visually inspect all lines in an area to evaluate the lines for any damage or potential problems. Drone inspection reduces man-hours and labor costs by automating inspections with low maintenance costs, saving approximately 30 to 50% of money and time.
Drones are used to monitor vegetation encroachment along power lines, especially in hard-to-reach areas. Capable of navigating between dense trees, as well as taking off and landing in tight places.
Drones make it easy to fly along power lines and then take high-quality video and pictures, and inspectors are able to collect better, more detailed data than they would be using traditional methods.
Drones reduce the number of personnel and ancillary equipment that must be on-site to conduct inspections, significantly reducing the overall complexity of the project.
A drone is so versatile, that it can be used to inspect power lines and power pylons for bird's nests, lightning strikes, rust/corrosion, and damaged bolts.
Determine the distance of vegetation from power lines. This information can then be used to create a plan for which vegetation needs to be cut immediately so as not to interfere with the use of the lines.
Drones conduct frequent, on-demand inspections to monitor the safety, reliability, and integrity of wires to improve efficiency and eliminate risk.
Use drones to capture the status of the grid from multiple angles to reveal any faults or defects and address them in a timely manner.
Use drones equipped with radiant heat sensors to obtain real-time temperature readings of power lines to immediately identify anomalies and avoid the risk of wildfires. At the same time, drone surveillance can monitor damage to power lines from hill fires caused by natural disasters, ensuring the safe operation of the power grid.
Commercial drones shoot over powerlines to obtain oblique imagery, which is then composited by third-party tools to generate 3D models. It can be used to calculate the height of the powerline and the ground, the distance from the powerline to the nearest obstacle, distance from the tower to another.

After acquiring the spatial coordinates of each sampled point on the surface of an object, a collection of points is obtained by a LiDAR drone , which is called a "Point Cloud". The point cloud is obtained by combining laser measurement and photogrammetry principles, including three-dimensional coordinates (XYZ), laser reflection intensity (Intensity), and color information (RGB). It can be used for powerline 3D visual management, powerline route planning, and designing.
A thermal drone can be used for measuring the heat emitted from powerlines in order to analyze the abnormal voltage and contact resistance. It helps the operation and maintenance personnel to check the defects in time.
DAI is a reliable drone manufacturer and solution provider. DAI drones are easy to operate and enable inspection teams to obtain high-quality data with basic training while standardizing data output and streamlining the process. Here are some key features:
DAI-FlightSurv is an easy-to-use surveying software that can be used effectively by beginners and advanced users alike. This 3D modeling and mapping software can be used as a mobile application for a single person or corporate clients with any number of users.
The CA-103 full-frame aerial camera is the best RGB camera for power corridor inspection. It has a 61-megapixel full-frame Exmor R CMOS back-illuminated image sensor and JAL-35 lens for high image quality, nearly twofold sensitivity, and low noise. Specifically designed for the DAI drones, CA-103 Aerial Camera 's vibration dampening plate uses four-corner protection technology to greatly improve the stability and accuracy of the drone when taking pictures.
MG-120 Gimbal Camera is a light and small HD gimbal camera developed by DAI. The camera integrates infrared sensors and optical sensors at the same time, which can be used for detailed inspection and abnormal point troubleshooting. Its 30x optical zoom sensor allows you to see objects in detail up to 2km. With the 640*512 infrared sensor, the MG-120 can detect and identify tiny anomalies in power lines at night or in low visibility.
DAI-LiDAR is integrated with GNSS INS to produce accurate position and orientation data. Equipped with a fiber optic inertial navigation system, DAI-LiDAR-LR is more stable, more anti-jamming, and more accurate with higher data accuracy than other LiDAR scanners . In addition, DAI-LiDAR-LR has a 3X higher point cloud density than other LiDAR sensors. The higher the number of measured points gathered by DAI-LiDAR-LR power line inspection, the more information it is possible to get out of the 3D model created in the end. What's more, DAI-LiDAR-LR can be quickly sorted to form an intelligent workflow, with fast processing speed and simple results production process.
