Powerlines Inspection

AAM’s power lines services reduce network costs and risk for power distribution and transmission companies. We leverage new inspection technology and techniques to inspect more network assets and assess more powerline vegetation infringements at a substantially lower cost.

Our aerial surveying team, who have flown 100s of thousands of power line kilometres, use multi-sensor cameras to capture network routes, asset condition and vegetation encroachment – all in a single inspection pass. This automated approach reduces the need for on-board linesman, increases asset coverage and improves reporting accuracy.

AAM can achieve four essential aerial inspections in one flight:

  1. Aerial inspection for asset condition and vegetation management
  2. LiDAR inspection for vegetation management and route and conductor mapping
  3. Thermographic inspection (IR and UV) for asset condition and fault detection
  4. Aerial photographic inspection for asset condition, easement encroachment and vegetation management

 

We also provide:

  • Modelling of captured inspection data for route planning, conductor mapping and powerline load modelling.
  • Automated reporting and work order creation optimises vegetation trimming and asset maintenance tasks with work crews.

AAM’s power line services deliver accurate asset and vegetation data—in one inspection pass— to reduce your network risk and maintenance costs. 

Applications

Corridor Planning

Corridor planning requires high resolution digital terrain models, even in densely forested areas, that allow accurate planning of power line and pipeline corridors. AAM provides terrain shape, existing conductors and vegetation imagery enabling you to optimise transmission routes and tower placement.

Conductor Mapping

A single pass of the survey aircraft captures high definition imagery and LiDAR. Terrain, easements, vegetation, buildings, land use, towers, conductors, even tiny fasteners, and site access are recorded, updating your GIS and preserving vital attribute information.

Conductor Modelling

AAM’s PLS-CADD engineers model your conductors to determine maximum line loads for specific temperature and wind conditions. Mathematical modelling removes the need for subjective field assessments which reduces risk, eliminates premature maintenance and provides an audit trail.

Vegetation Intrusion

Mapping easements and identifying vegetation infringements reduce bush fire risk, unplanned outages and improve safety. By incorporating analytics to predict vegetation growth, infringement reports place accurate and detailed information in the hands of your vegetation contractor, improving the efficiency and effectiveness of your vegetation pruning programs.

 

Asset Condition

Simultaneous capture and onboard processing of high definition imagery, IR and UV data, records asset condition and automatically classifies fault types. This reduces reliance of an onboard linesman and increases asset inspection coverage.

Accurate asset condition reports allow you to conduct desktop asset studies, minimising risks from service disruption, non-compliance with regulations while improving employee and public safety.

Geo-referencing technology identifies fault locations for your work crews, in addition to the fault source and what needs to be replaced.

Fault reports include

  • Visible faults: onboard processing of high definition imagery records asset condition and identifies visible faults, even for difficult to access locations.
  • Corona faults: UV cameras detect insulator cracks, contamination, corrosion and poor grounding structures.
  • Mechanical faults: high definition video and still images capture loose bolts, cracks, faulty spacers or dampers and missing signs.
  • Overheat faults: thermal IR identify bad splices, mid-span joints, connections, loops and fittings.

Aerial Survey

AAM’s aerial survey experience enables data capture for essential aerial inspections in one flight:

  1. Aerial inspection for asset condition and vegetation management
  2. LiDAR inspection for vegetation management and route and conductor mapping
  3. Thermographic inspection (IR and UV) for asset condition and fault detection
  4. Aerial photographic inspection for asset condition, easement encroachment and vegetation management

 

Drawing on our experience and methodology for power network monitoring, we select the optimal arrangement for inspection and data acquisition on each project:

  • platform for optimum mode of data capture: fixed wing, helicopter and terrestrial
  • sensor type: multiple sensors are available to capture video, images, LiDAR, infrared and ultraviolet
  • acquisition characteristics: flight speed, altitude, pulse rate settings and field of view
  • classification accuracy: level needed to ensure the resulting outputs are of the highest quality and can be delivered in a format that is fit-for-purpose.

SWE Quad 400 IR/UV Sensor

The ideal choice for power line inspection, the quad sensor incorporates full high definition video, 36 Megapixel photography, thermal IR at 1024x768 pixels and corona bi-spectral UV.

The long wave thermal IR detects and classifies thermal anomalies on power lines and the UV radiometric system captures real time temperature measurement in order to classify corona discharges from broken insulators or loose strands.

Geo-referencing capabilities enable GPS positioning of power line assets which, when combined with mapping software, determines the exact location of a fault.

LiDAR

AAM introduced LiDAR (Light Detection and Ranging) to power line LiDAR inspection in 1998. LiDAR captures highly accurate and complete definitions of the power line corridor, mapping conductors, structures, undercrossings, vegetation, buildings and terrain in a single pass.

All aerial inspections are supported by a full range of allied technologies: mobile laser scanning, weather stations, satellite and UAVs.

Post Capture

AAM’s onboard data processing and web services deliver your reports and inspection data quickly and easily.

Condition reports, containing geo-referenced asset images and location data, integrate with your corporate asset management and work order systems to streamline maintenance processes.

AAM’s GEOCIRRUS cloud platform, combines web mapping tools, inspection data, condition reports and vector layers that help you make better decisions. GEOCIRRUS is a complete solution. Stream your inspection data, display condition data with other GIS layers, query and analyse datasets, and produce workflows that integrate with your corporate GIS and ERP solutions. Using GEOCIRRUS, your staff and contractors can access asset and vegetation data and reports in the office or field.

AAM’s power line services deliver accurate asset and vegetation data—in one inspection pass— to reduce your network risk and maintenance costs.
