Hydro-Québec, Canada’s largest producer of electricity and one of the world’s largest producers of hydroelectricity, and DRONE VOLT, have signed a memorandum of understanding to reach an agreement on the exclusive industrial development and marketing of a drone, designed to inspect high-voltage power transmission lines of a drone.


The LineDrone is dedicated to high-voltage power lines inspection, produced in partnership with Hydro-Québec.
Its main features are:
  • Immunity to 400 kV electromagnetic fields
  • Landing on electric conductor and motorized movements on the lines thanks to a motorized rolling system
  • UAV with 8 motors and propellers


Thanks to its two on-board sensors, the LineDrone can carry out different inspection missions.
  • LineCore: measurement of corrosion. Checking the thickness of the zinc layer and the thickness of the steel.
  • LineOhm: measurement of electrical resistance. Checking the electrical resistance of junction sleeves for electrical cables and defective equipment, lack of grease…


The LINE DRONE can perform very precise measurements on working power lines using sensors developed by Hydro-Québec Research Center teams, which avoids interruption of the electricity service.
This solution:
  • Avoids power outages
  • Limits human risk (no more climbing on electric towers)
  • Reduction of inspection cost
  • Reduces the impact of GHGs (helicopters are no longer needed for these operations)
