In Spring 2017, Aeriosense provided its services to Allteck Line Contractors Inc., an industry leader in transmission line maintenance whose expertise ranges from design and installation to maintenance and repair of high-voltage infrastructure. Allteck was looking to achieve more efficient, more cost-effective detailed inspection of high-voltage transmission lines.

Using Aeriosense's automated drone inspection solution on an 18 km, 138kV transmission line section near Dawson Creek, Allteck was able to significantly reduce both the cost and time of inspection, as well as increase safety and reduce disruption to local landowners.

The Challenge

Conventional detailed inspections require up-close visual assessments of a transmission tower's key components. Typically, these inspections are done by either physically climbing the transmission tower or by using a bucket truck, both of which are expensive, time-consuming, and have associated safety risks that need to be mitigated.

Single pole structures can only be climbed part way while energized, giving only marginal advantage over ground-based inspection. While bucket trucks, are costly and subject to limited access in challenging terrain. The transmission line in this project goes through a rural area with farm fields and ranches, so right of way (ROW) access must be coordinated and disturbances must be minimized.

Automated Drone Inspection Tool

Aeriosense's automated drone inspection tool employs a drone equipped with visual and IR cameras, which is automatically guided to and around the structure on a pre-defined flight path. The system was used to inspect 8-12 poles from a single take off location before being taken to the next section of the transmission line.

This system allowed high-quality visual and infrared imagery to be collected and analyzed in detail without the need to climb the poles or drive a bucket truck over the farm fields.


Allteck's experience with Aeriosense's approach was extremely positive. Automated drone inspection significantly reduced project costs and disruption to local landowners and dramatically increased the speed and safety of the detailed inspection of the transmission line, all while producing equivalent quality of inspection compared to conventional methods.

Inspection of the 18km stretch of 138kV line, which previously took 30 days, was completed in under 5 days, with separate inspection flights for detailed visual and thermal imaging. Significant cost savings were achieved compared to conventional inspection methods while avoiding cost overruns due to ROW access issues.

Key Results:

  • Inspection time reduced by 85%, inspection cost reduced by 80%.
  • Inspection speed of 1km/hr, 10 structures/hr.
  • Eliminated safety risks associated with climbing and bucket truck inspections,
  • Minimized disturbance to landowners,
  • Reduced time spent on project coordination,
  • Equivalent inspection quality compared to conventional inspection methods,
  • Inspection data logged, to allow future condition trending
"Compared to the bucket truck inspection we are seeing significant cost reduction in the detailed inspection using the Aeriosense tool. It also gets the job done faster, freeing up our bucket truck and personnel for other jobs. The other benefit is we don’t have to worry about rutting out and damaging the farmers’ fields"
- Kevin LaChapelle, Regional Manager, Allteck


Future Plans

Given the strong results achieved during this inspection, Allteck plans to make automated drone inspection part of their routine inspection for the 18km transmission line near Dawson Creek. Allteck is also exploring the possibilities of applying Aeriosense’s automated drone inspection tool to other projects in the future.

NextGen Quiet High Endurance Heavy Lift MultiRotor


Hi there friendly people of DIY Drones

I've been using and building drones for a few years now, and general shortcomings, I find are: noise, flight time, payload capacity, waterproof space for sensor and computing additions. These shortcomings of course all have good reasons to be there.

Some of the things I've done in the past are: made a really big rig (2m span) that's capable of ~1hr hover, and a few kg's payload; made some smaller rigs with some interesting technologies such as vertical surface extended docking (windows/walls). After a whole lot of effort and various iterations, myself and fellow collaborators at Crimson UAV have come up with the Talon6UAV. It is designed to be a premier aerial photography, survey, and R&D drone.

Some of the key aspects are:
    Quiet Operation: Large 26" carbon props operated by high torque motors in an alternating overlapping pattern enables a stable and quiet flight
    Endurance: Lightweight and elegant design coupled with up to 888Wh of battery capacity enable long flights ~40minutes
    Low Downtime: A rail and car battery changing system enables seamless no nonsense battery swaps to keep your business in the air
    Development: Dedicated waterproof space and power supplies for companion computers and sensing equipment allow this craft to be quickly modified to your needs.    

I would really appreciate any feedback, thoughts or ideas from all the knowledgeable people here.
