Inspection of wind turbines

German Copters DLS GmbH works with leading system providers to inspect wind turbines. The skills in flying drones and the engineering knowledge of German Copters are combined with the specialist knowledge of the solution providers for maximum customer benefit. A high data quality, efficiency in the execution of the job and the reduction of downtime are the most important criteria when working on wind turbines. By using AI and experienced rotor blade specialists, we increase data quality while reducing inspection costs at the same time.

Integration of lightning protection inspections

According to the industry portal, every wind turbine is struck by lightning around once a year, usually on a rotor blade. If the system is not adequately protected against these lightning strikes, it can lead to considerable damage, including bending of the rotor blades or failure-causing fires

The tests should be carried out in accordance with the certified lightning protection concept of the wind turbine or in accordance with DIN EN IEC 61400-24 VDE 0127-24. Wind turbines are normally classified according to the highest risk level (lightning protection level) LPL I and the corresponding lightning protection class I. It should be noted that annual visual inspections and full inspections must be carried out every two years

Up until now, extensive inspections had to be carried out on ropes. German Copters is now performing a non-contact lightning protection measurement (LPS) verified and validated by TÜV SÜD with a specialized drone. This saves time and money compared to conventional methods.

German Copters in TV
01-20-2022 Combatting animal diseases with the help of our drones was now also a topic on MDR television. The film team filmed us at work, and we answered questions. With another drone, we produced some film sequences ourselves, which were then also shown in the television report.

German Copters in the Press
01-14-2022 Today a nice article was published in the Sächsische Zeitung about swine fever and how we help to fight it with our drones.

From December 2021 to mid-January 2022, we searched an area of 18,000 ha in Saxony and covered a VLOS flight distance of 1,400 km.

Fight against animal disease
01-03-2022 German Copters uses drones to help fight African swine fever. In December alone we searched over 140 km2. During the search, we flew over 1,000 km VLOS and documented 40 sites. We were able to search this large area, not only because we have experienced pilots, but because flight planning, process control and documentation are largely automated.

Merry Christmas
12-23-2021 For us as German Copters, 2021 was an exciting but very successful year. Even if Corona was raging and we were affected by it, we were able to more than double our sales. We found new employees, worked on new projects, invested in technology, and signed sponsorship agreements with interesting sports clubs in the region. The planning for the coming year is almost complete. If we only successfully complete 20% of the planned jobs in 2022, we will probably double our sales again in the coming year. It remains exciting.

But now it is time to pause for a moment, use the holidays together with the family for some rest and recharge your batteries. We also think of our employees, customers, partners and friends. Health is most important. We wish everyone a Merry Christmas and please stay safe.
