Power Line Inspection

Inspection of power lines across Europe

Since 1992, Valair Helicopters has been the number one choice for all forms of airborne surveillance and inspection work. We are the first point of contact for infrastructure companies and public corporations and are also distinguished by the comprehensive range of services we offer.

Valair AG first began inspecting overhead power lines in 1992; back when the cables were photographed with a handheld camera and the main focus was on documenting damage to the concrete masts. Today, state-of-the-art technology is used to inspect high-voltage power lines including gyrostabilised multi-sensor camera systems, GPS data and special analysis software. We offer a comprehensive package solution for the utilities segment.

Comprehensive offer of services
  • Flight planning for power line inspection
  • Flying over power lines with gyrostabilised camera systems (multi-sensor)
  • Analysis of any identified faults and preparation of a damage report

During a flight, we examine the overhead power line with infrared technology (thermal imaging), corona discharge images and HD video footage. Our specialists will assess any visible damage on site. We will immediately inform you of any serious defects. An integrated camera takes high-definition photos wherever needed for subsequent detailed analysis.

All captured material is then evaluated by specialists at our headquarters. These not only produce comprehensive documentation of all problem areas identified, but also prioritise the damage and develop suggestions for carrying out maintenance work. At a final presentation we will carefully review the documentation with you and make adjustments to optimise our continued cooperation.
