By using sUAS & maintenance optimization strategies, utilities can budget condition-based repairs and prioritize maintenance on distinct identified

structures, vs percentage of grid, resulting in more ‘critical repairs’ completed per year, which meet traditional maintenance minimums.

Case Study for Long-Range Beyond Visual Line of Sight Project

Helicopters In Transmission Inspection• Helicopters will always have a place in

transmission construction and repair• Transmission inspection services will be

predominantly replaced with Unmanned Aerial Systems (UAS)

• Safer• Higher resolution• Repeatable• Autonomous • Ever increasing variety of sensor technologies

• UAS use limited by inspection distance and cost

Beyond Visual Line of Sight Inspections

Current FAA Part 107 require an elusive waiver to fly beyond the visual line of sight (BVLOS) of the pilot

FAA is starting to support more test cases proving the safety of flying safely BVLOS

There are many approaches to safely flying BVLOS (radar, ADS-B, remote ATC). We have been testing the Visual Flight Rule (VFR) approach

In comparison to overall costs, the economics of helicopters to UAS starts to tip in the favor of UAS at 10 mile inspection flights

BVLOS adoption will be process of sensor technology, flight technology and regulatory process

• Cellular• Bonded Cellular• Microwave• Satellite • Combination• Live Video Feed• Current technologies working at 5 miles

Control• Line of Sight (LOS)

Process to Successful UAS Program Development

Needs• Identify data users• Optimize data collection efforts to meet the needs of most users

Quality• Precision, Accuracy, Reliability, Repeatability and Data Security• Data Quality Objectives (DQOs)

Sensors• Select sensors to best meet DQOs• Understand optimal flying conditions for sensor (altitude, spacing, speed, etc.)

Craft• Initial screening of UAS craft to carry sensors for expected mission length• Final selection based on environmental conditions (weather, portability)

Product• Field check procedures for validating data collection• Processing of data for specific for users (.las, DEM, .dwg)

Workflow• Document workflow from flight operations to data storage• Encourage user feedback for continuous workflow improvement

UAS Sensor Technology

LiDAR• Terrain mapping• Volume quantification• Ground surface mapping• Change detection• Feature detection• Permitting• Vegetation Encroachment

Multispectral / Hyperspectral• VNIR and SWIR• Very high resolution (0.1

m)• Vegetation health

Corona• Coronal discharge• Daylight Use• Video of discharge and

emitter

Magnetic• Subsurface Anomaly• Exploration• Pipeline location• Well head clearance

Thermal• Water temperature• Heat loss• Mechanical stress• Pipeline leaks

Imagery• Vegetation assessment• Cultural resources• Photogrammetry• Infrastructure Condition

Inspection

LiDAR versus Photogrammetry

• LiDAR is more accurate• Penetrates vegetation• Classification of features• Planimetrics• Not impacted by shadows• Construction details• PLS-CADD Ready

UAV Image Example from Phase I 100 Mega

Pixel Camera at 20 meters

Image Zoom with

1.7 mm GSD

LiDAR Data Collection• Transmission lines• Distribution lines• Substations

Choice of craft is based primarily on payload and endurance

Use over critical infrastructure should also evaluate onboard redundancy in electronics and flight motors

Imagery and LiDAR need stability Autonomous versus pilot control Mission simulation Emergency landing considerations

UAS Craft Selection Considerations

BVLOS Flight Mission• 10 mile survey in central Nevada

• Performed with Nevada Institute for Autonomous Systems (NAIS)

• Flight operations performed by AviSight a DataSight partner

• LiDAR and imagery collect

• Pulse Aerospace Vapor 55 with RIEGL VUX-1 UAS LiDAR

Mission planning

• UAS Altitude• UAS velocity• Flight pattern• Data density• GPS RTK Base Station• Ground Panels for calibration• Ground shots as quality

control• Flight simulation

Data Collection Mission Planning for LiDAR• Density – Points per square meter

(ppsm)

• Field of View

• Number of returns

• LiDAR pattern

• LiDAR intensity

• LiDAR wavelength

• Colorization

• RTK versus PPK• Core Station

• Calibration• Quality Control• Point cleanup• Classification• Planimetrics• Digital terrain model (DTM)• Digital elevation model (DEM)

GNSS Antenna

LiDAR Point Cloud Ready for Evaluation

Data Evaluation – Data Density Drives New Methods

The automatic analysis of images and videos by computers for event detection, object recognition, tracking, etc.

Achieved thru writing computer programs that apply filters to remove noise and look for patterns and anomalies.

• Reading license plates as you pass thru toll gates• Reading money inserted into vending machines• Inspecting apples to determine if there are bruises• Warning drivers when they are drifting out of their lane• Facial recognition/biometric security checks

…and many more

AI or Computer Vision is used in many places

Simple Example –Woodpecker Holes

IncludeStep 1. Train the model

Exclude

AI Program analyzes image: highlighting holes that are over 1” wide

(yellow) highlighting holes that are over 2” wide (red)

Step 2: Run AI Pattern Recognition Program

Step 3: Review Results

Inputs: Pole 7-76-114 today and from an image 12 months ago

Step 1. Train the model – (model is already trained)Step 2. AI Program analyzes image

A) highlighting holes that are 10% larger B) highlighting new holes

Step 3: Review results

Insight into Action – only ”active” poles need treatment

Woodpecker Inspection – Part 2

Step 3: Review Results

Insight into Action – only ”active” poles need treatment

Inspection Workflow

UAS offers a technology to safely collect higher quality data BVLOS technology is advancing and supporting regulatory adoption Understanding data needs and quality is part of UAS mission planning Data management has to be part of the planning process Larger data sets will likely require some degree of automation Long-term goal is better use of data to optimize uptime and increase worker safety
