Overview

Specialised expertise for grid operators.

Aerial power line inspection — medium and high voltage — is essential to ensure the reliability of the distribution and transmission network. Professional drones now represent the most effective solution for this mission.

Equipped with high-definition cameras, thermal sensors, LiDAR and specific measurement probes, our drones perform precise diagnostics in complete safety, without service interruption or human exposure to hazardous areas.

What we deliver for you.

Mission 01

Visual & thermal inspection

High-resolution inspection of pylons, cables, sleeves, insulators and protection equipment. Detection of defects invisible to the naked eye.

On-board thermography reveals abnormal heating (faulty connections, phase imbalances, overloads) before failure or incident.

Mission 02

Grid integrity measurement

Non-destructive, live-line evaluation of compressed joint sleeve electrical resistance, enabling precisely planned maintenance operations.

Early detection of corrosion and measurement of residual galvanic protection thickness on conductors.

Mission 03

DLR sensor installation

Installation of Dynamic Line Rating sensors directly on live conductors, without power interruption or ground-level human intervention.

This innovative method significantly reduces operating costs and accelerates the modernisation of electrical infrastructure.

Mission 04

Mapping & vegetation monitoring

LiDAR and photogrammetric mapping of thousands of kilometres of lines, with RTK system for centimetric accuracy.

Precise measurement of vegetation near conductors — arc flash risk prevention and pruning planning.

Mission 05

Maintenance & works supervision

Verification of maintenance works and services carried out by your operators or subcontractors.

Timestamped, georeferenced digital archive, comparable from one campaign to the next.

On-board technology

Hybrid live-line inspection drone.

For the most demanding missions, we deploy a flying and rolling hybrid drone, specifically designed to operate safely on live transmission lines, from 120 to 315 kV.

  • Hybrid flying-rolling: lands on lines and moves along the conductor via a motorised system.
  • Electromagnetic immunity: operates live up to 315 kV and 2000 A.
  • LiDAR-assisted piloting: increased stability during critical landing and take-off phases.
  • Connectivity > 1 km: reliable communication despite perturbed electromagnetic environment.
  • Low power consumption: long-distance inspection thanks to efficient rolling.
  • Interchangeable probes: electrical resistance, galvanic corrosion, DLR sensors.

Non-intrusive analysis, unmatched precision.

Our hybrid drone carries measurement probes developed specifically for live-line power inspection. Precise, non-destructive analysis, without outage.

Sleeve resistance measurement

Non-destructive evaluation of the electrical resistance of compressed joint sleeves on aerial conductors. Enables precisely planned preventive maintenance and avoids unnecessary interventions.

Galvanic corrosion assessment

Early detection of protective zinc layer degradation. The probe checks and measures the residual galvanic protection thickness, without outage or human contact.

DLR sensor installation

Installation of Dynamic Line Rating sensors in minutes, directly on active lines up to 765 kV. Key for smart grid expansion.

High-resolution thermography

Coupled with visual inspection, the ITC-certified thermal camera reveals overheating, hot spots and invisible electrical defects — before they cause a failure.

Operational advantages

Why drones change the game.

Human safety

No more technician exposure to live-line or height work.

Time savings

Hours-long inspections replacing multi-day operations.

Cost reduction

Up to 70% savings versus classic methods (helicopter, rope access).

No outage

Inspection and intervention with no service interruption for your subscribers.

For live-line measurement and DLR sensor installation missions, Skyrider Inspection operates in partnership with a European leader in industrial drones, deploying patented equipment and technology proven on the world's largest power networks. You benefit from the flexibility and proximity of a local Croatian team combined with the strength of a top-tier technology ecosystem.
