Application of UAVs Transmissionand Distribution power lines inspection


Transmission Line & Distribution Service

Using drones in transmission & distribution today both opens up new possibilities and replaces existing work. Without drones, inspections are typically completed manually, using climbing, bucket trucks, long-range photography or helicopter. Clearly, manual inspections involving climbing or using buckets introduce hazards that are avoided with drones. Ground-based data collection typically lacks the detail and flexibility that a drone can provide. Helicopters can capture data quickly and over large areas of land, but they are expensive, can’t operate near residential areas, and often miss finer defects.

Use cases for drones in T&D

Transmission power spot check.
Regular ground patrols.
Substation upgrades, maintenance & inspection.
Storm restoration.
Urban or suburban vegetation.
Everything else.

“One of the most valuable things the drone does is allow us to inspect infrastructure without having to shut it down. This saves us hazardous manhours, improves turnaround time by several days, and eliminates paperwork.”

4 Benefits of transmission line & distribution by using drones



Collect a higher level of detail - missing pins, rust, and damaged insulators


Save time and cost with drone inspections


Get a close-up view of a potential defect without climbing or using a bucket truck.


Quickly access to areas blocked by water or fallen trees, etc, after a natural disaster

Corona discharge detection

Be an electrical discharge caused by the ionization of the air surrounding the conductors.

Produce a purple glow and can cause loss of power, cracking noise, radio interference, and ozone gas production.

Provide the co-location of electric shocks and hot spots to better understand the cause of a fault.


  • Maximize service time

  • Easily access dangerous areas

  • Identify wear, detect corona discharges, electrical malfunctions or even assembly faults


Power line stringing

Wire high voltage lines from one high voltage tower to another, in a safer, faster and less expensive way than traditional stringing (helicopters, manual stringing).

Load a very thin, light, and ultra-resistant cable guide that is laid on the transmission tower in order to reach the crew on the ground that will install the final cable.


  • Avoids human risks

  • Reduction of operational costs

  • Quick installation


Mapping of power line networks

Be equipped with a lidar or a RGB camera and a RTK system provides high-resolution images at a reduced cost and safely for 3D mapping.

Allow the inspection of thousands of kilometers of electrical lines in order to optimize the monitoring and the maintenance plan of the network.

Allow vegetation monitoring, verification of maintenance works and services performed by operators or external companies as well as checking the general condition of the power lines.


  • Cost reduction

  • Time saving

  • No power outage

  • Avoids human risks
