Technostrobe manufactures protective lighting systems for tall structures that represent a potential obstacle to air traffic. The company’s mission is to provide equipment that lets our clients benefit from the latest and most-effective technologies on the market.
The company says it works to be the leader in protective lighting systems designed for the broadcasting, telecommunications and wind farm industries. The company provides these explanations as guidelines to help developers, project engineers and designers when considering the installation of obstruction lighting for a wind farm.
A wind farm may be defined as three or more wind turbines, each with a total height equal to or less than 150m (500ft). Implementing the following guidelines will help pilots recognize the obstacles as a wind farm as opposed to other types of obstructions. In addition, the application of these guidelines can vary depending on terrain features, geographic location, overall layout of the structures, and normal approach angles.
Perimeter –The group of wind turbines that make up a wind farm shall be indicated to pilots by the installation of red flashing beacons (L-864 or CL-864 medium intensity) on specified wind turbines on the perimeter of the wind farm.
Distance – The wind turbines on which the red flashing beacons are installed shall be spaced at a horizontal distance in the order of 900m (1/2 statute mile) for given directions of aircraft approaches.
Highest point – The dominant [highest in absolute height] wind turbine within the wind farm also needs to be lit with a red flashing beacon. This requirement for lighting depends on the degree of dominance deemed to produce a hazard to air navigation.
Special considerations – Because of the variations in wind farm configurations, the provision of lighting shall also be subject to a risk assessment, taking into account such factors, such as the:
• General profile of the group,
• Location of the wind farm in relation to nearby airports or recognized VFR flight routes,
• Anticipated air traffic.
Synchronization – All indicator lighting provided for a wind farm shall flash simultaneously.
