Power line inspection

  • Power line inspection

  • Power line inspection

The use of drones for power lines inspections has become increasingly popular mainly due to a reason – it represents the most cost and time efficient way for conducting power line inspection, while minimizing the hazards traditionally associated with the manned inspections of power grid. Since 2015 EWATT UAVs flew over 15 000 km of power lines, and 4000 transmission towers providing the clients valuable data, which prevented many potential power outages and grid failures.

The most common objectives include documenting:

  • missing or broken parts of the power line infrastructure, both the transmission towers and the overhead lines

  • overheating elements of the grid

  • partial discharge of the grid

  • power line sag and proximity of the physical objects such as trees, ad banners etc.

The payload determines the aircraft that is deployed for the mission. For long haul flights such as monitoring of the corridors’ space, the fixed wing UAVs is the most efficient solution. Because of its great maneuverability and ability to hoover the multi-rotors, it provides the best results. EWATT multi-rotor platforms thanks to greater payload capacity that is able to carry even the heavier payloads such as LiDAR systems. The pictures, footage and point clouds collected during the inspections are processed by experienced team of EWATT ‘s experts, who produce the final reports according to the standards recommended by the clients.
