Poles and towers
Visible structural condition, hardware arrangement and areas requiring closer review.
Power line inspection
Inspect critical line assets with safer, closer visibility.
Drone-based thermal and high-resolution visual data collection for transmission and distribution infrastructure, supported by engineering review and prioritised reporting.
Engineering-led inspection
Aerial inspection support
Detailed evidence without relying only on ground-level visibility.
Drones can capture close visual and thermal evidence from elevated, remote or difficult-to-access line assets. The inspection plan is developed around voltage level, operating status, access, terrain, flight constraints and the client’s objectives.
Scope and capability statement: ThermoSky will confirm the sensors, flight method and deliverables for each project. Ultraviolet corona inspection, LiDAR, automated defect recognition or other specialised capabilities are not included unless specifically quoted and supported by the required equipment.
Inspection areas
Assets and conditions that may be reviewed from the air.
The exact asset list and required viewpoints are agreed during inspection planning.
Joints and connectors
Temperature comparison of clamps, jumpers and connection points under suitable loading.
Conductors and fittings
Visible abnormalities, fittings, spacers and other line components within the agreed scope.
Insulator assemblies
High-resolution observation of insulators and associated hardware from planned viewpoints.
Cross-arms and line hardware
Condition evidence for mechanical components, attachment points and fittings.
Vegetation and corridor conditions
Encroachment observations, access concerns and visible clearance issues for review.
Thermal inspection
Compare similar components to identify abnormal heating.
Thermal data can support the review of loaded connectors, joints, clamps and other current-carrying interfaces. Interpretation considers loading, emissivity, viewing angle, weather and comparison with equivalent components.
- Connector and jumper temperature comparison
- Geotagged thermal and RGB evidence
- Observation classification and priority
- Recommended verification or maintenance follow-up
High-resolution visual inspection
Bring difficult components into clearer view.
Planned viewpoints can provide evidence of visible component condition and help direct where detailed field inspection is most valuable.
Insulators and fittingsReview visible damage, irregularity, contamination or missing components where image quality permits.
Structures and hardwareObserve corrosion indications, displaced parts and structural areas that warrant closer assessment.
Conductors and attachmentsCapture visible evidence around clamps, jumpers, spacers and attachment points.
Vegetation and accessDocument corridor conditions for clearance review and maintenance planning.
Mission planning
Inspection scope shaped by operational reality.
Electrical line work requires careful coordination. ThermoSky confirms access, hazard controls, flight restrictions, operating conditions and data requirements before mobilisation.
Voltage and operating condition
The line voltage, energisation state, loading and required safe clearances affect the mission.
Route and terrain
Access points, vegetation, terrain, structures and line length influence flight planning.
Safety and permissions
Site controls, airspace requirements and coordination responsibilities are defined in advance.
Required data detail
Target components, image resolution, thermal requirements and asset identification are agreed.
Technical reporting
From corridor imagery to traceable findings.
Deliverables are agreed before the mission and may include asset references, geotagged imagery, thermal observations, condition notes, priorities and recommended follow-up actions.
Asset reference
Tower, pole, span, structure or component identification where available.
Evidence
Thermal and/or visual images with clear annotations.
Observation
Concise description of what is visible and relevant limitations.
Priority
Suggested level of review based on apparent significance.
Follow-up
Recommended field verification, monitoring or maintenance consideration.
