MADE IN THE USA
Live-line, no-power-down inspections
LineDrone lands directly on energized power lines up to 400,000 volts and 2,000 amps, performing inspections without shutting off electricity or needing helicopters
Advanced sensors for safety-critical data
Features LineOhm for checking connector resistance and LineCore to detect corrosion—non-contact, real-time diagnostics that help prevent power failures.
Flies, lands, then rolls along the line
Flies like a drone, then shuts off its propellers and rolls along the line—conserving power and covering long spans efficiently.
Built to handle high-voltage stress
Works reliably on lines from 120,000 to 400,000 volts, immune to electromagnetic interference and safe around currents up to 2,000 amps.
Fast setup, long-range control
Deployed in minutes with over half a mile of wireless range, lidar sensors, and assisted piloting for precision in tough terrain.
Benefits
With its sensors developed by Hydro-Québec’s research centre, the LineDrone takes highly accurate measurements on single-conductor power lines while they are in service.
The benefits of this solution:
- The precise information obtained via LineDrone and the LineOhm sensor is an essential input to uprating the capacity of power lines, which enables utilities to safely transmit more energy through the existing assets.
- Eliminates line de-energisation and network operating constraints
- Limits human risk
- Reduces inspection and team deployment costs
- Minimises greenhouse gas emissions. In fact, eliminating a helicopter represents a reduction in greenhouse gases of one to two tonnes of CO2 per day of operation.
- No shutdowns required — keep the grid live during inspections
- Zero helicopter risk — safer for crews and lower cost
- Pinpoint faults early — detect splice failure and corrosion before they cause outages
- Eco-efficient — low energy use with rolling motion
Features
The LineDrone is a dedicated system for inspecting high-voltage power lines, developed by Drone Volt in partnership with Hydro-Québec.
Its main features are:
- Mechanical and functional integration of precision measurement probes for non-intrusive inspection of high-voltage lines.
- Protective cage and mechanical design for contact with transmission lines from 120 to 315 kV, up to 2000 A, while ensuring the system’s immunity to the various electromagnetic disturbances generated by high-voltage lines.
- Landing on overhead conductors and moving on single-conductor lines thanks to a motorised rolling system.
- Drone with redundant 8-motor architecture, offering the capacity to safely carry measurement probes weighing up to 2kg.
- Communication system resistant to electromagnetic fields disturbed by high voltage.
- Rapid deployment capacity for optimised operational results.
Sensors
Thanks to two types of on-board sensors, developed by Nucleom and Hydro-Québec, the LineDrone can carry out a range of non-destructive inspection tasks, while documenting the results of analyses with a high degree of accuracy.
LineOhm: Hydro-Québec’s patented technology, enables the electrical resistance of compressed joint sleeves on electrical conductors to be assessed non-destructively. Inspections using LineOhm provide a quality of measurement that enables the integrity and useful life of equipment to be assessed. This is essential data, enabling programmed maintenance operations on lines to be planned as accurately as possible.
LineCore: provides a non-destructive method for under-voltage corrosion assessment and early detection of zinc layer degradation. The LineCore sensor checks and measures the thickness of the residual galvanic protection.
