The inspection process

We can offer services regardless of your location in the world.

You specify the section of power line to be inspected. We then fly this route
under suitable weather conditions and store all data in digital format. An authorized
representative may accompany the inspection.

An initial assessment is made during the inspection by an electrical specialist
in the helicopter.

The speed of inspection depends on the number of components and problems detected.
After the flights we perform a final assessment and shortly there after you receive
a report with a copy of all the data.


The data includes a complete documentation of the flight, including a thermographic
images (radiometric data) and high-resolution video images. The data is correlated
with the aid of overlaid GPS coordinates that can be linked to a digital map. You
will receive all data on DVD.

The report shows you all components that require attention. Defects are marked
on the digital map and the corresponding photos are provided. Requirements.

  • Good weather conditions
  • Cloud cover / weather conditions must not allow direct sunlight to interfere with the thermographic process
  • Performing the inspection during high load periods is optimal for potential failure point detection


The increased efficiency of airborne inspections makes this service very economical.
Airborne inspection proves its value particularly in inaccessible areas such as
mountainous regions.
