Drone Inspection for Wind Turbines

Using state-of-the-art drone technology — including DJI systems with high-resolution Zenmuse cameras such as the Zenmuse Z30 (30× optical zoom) — regular drone inspection in the sense of predictive maintenance enables early detection of damaged areas on all externally visible components. Damage is documented in detail and at close range, allowing fast and effective assessment and follow-up — without rope access, cranes, or elevated platforms.

Due to their exposed location, wind turbines are particularly susceptible to lightning strikes. In accordance with DIN EN 62305 and applicable operator standards, the lightning protection system of a wind turbine must be inspected regularly — typically every one to two years. Lightning receptors in the rotor blades and the conductor systems in the tower are especially critical inspection points.

Drone inspection offers a fast, cost-effective, and safe alternative to conventional methods: high-resolution cameras detect damage to lightning receptors, corrosion on conductor systems, and structural anomalies on rotor blades — without rope access or elevated platforms. This allows the statutory inspection requirement to be fulfilled efficiently and with full documentation.
