Aerial Infrared (IR) Inspection Service for Power Lines
WORK PROCESS & INFRARED IMAGING EQUIPMENT
Our infrared technicians and aerial mounted camera system are deployed using a rented helicopter local to your area in order to minimize costs. The flight path is determined through consultation and based on your needs.
We use the FLIR Systems 2000 series infrared camera, which is remotely controlled and has a thermal resolution of 1/10°F, and a pictorial resolution of 525 lines per frame (560 CCIR) with 352 elements per line (428 CCIR). It utilizes a Mercury, Cadmium, Telluride (HgDcTe) 2×4 TDI detector array with an IR Special bandwidth of 8 – 12 microns. This camera renders an image of an object’s thermal emissions in shades of black to white . . . white representing hot and black depicting cold. The data is then digitally recorded for processing. The FLIR 2000, mounted externally on the helicopter, is remotely controlled by the thermographer inside the cabin. LCRS rate stabilization assists the Thermographer in manual target tracking by dampening the effects of aircraft motion.
Advantages of using our aerial mounted infrared camera include:
- Increased safety due to further distance from the lines than the typical hand held camera inspection.
- Optical zoom lens allows us to acquire high resolution close up images (not just a blown up digital image )
- Mobility of the mounted unit and zoom lens means we fly faster than the typical infrared survey out of the window. Flight speeds average 45 knots and this save you valuable helicopter dollars!!
- We find more problems than typical hand held IR surveys because we have over 10,000 hours of aerial power line inspection experience, certified thermographers and right equipment for the job.

Our infrared (thermal) reports are concise and to the point, making anomaly location easy to determine and facilitate repairs. Your report will include:
- A detailed easy-to-read inspection report including:
- Written narrative of the survey
- Report form for every anomaly detected during the inspection
- Infrared DVD video of the entire inspection
- Hard copy and electronic version of the entire report
- A report sheet accompanies each problem which includes:
- Digital visible light photograph, color thermogram and black / white thermogram images
- Complete temperature analysis of the anomaly utilizing ambient temperature or conductor temperature for comparison
- GPS locations of the anomolies
- Infrared data
