Inspections
ENERTRAG Operation's inspection department is specialized in various areas of inspection: Machine inspections, gearbox and rotor blade inspections, vibration measurements and also DGUV-V3 inspections. The accreditation according to DIN EN ISO/IEC 17020 underlines the high level of quality.
Drone inspection
Rotor blade inspection and LPS measurement via drone: Not only more accurate, but also more efficient.
Regular maintenance and inspections are necessary to maintain the value of a wind turbine - for example, a precise inspection of the rotor blades. Innovative drone technology not only protects employees, but also offers a higher error detection rate thanks to excellent image quality and autonomous flight patterns.
Safety checks
Safety is the be-all and end-all in wind turbines. This is why, in addition to other tests, annual safety inspections of certain components are required in accordance with the Ordinance on Operating Sites.
