TÜV SÜD examined the concept for the temporary lighting installation on the Fröttmaning wind power turbine, accompanied all the preparations and installment, and completed the final onsite tests. The tests focused on possible effects on the wind turbine’s stability, the reliability of the energy transfers from the stationary tower to the rotating blades, and the reliable functioning of the safety systems. “The rotor blades, for example, move into. Martin Webhofer of the wind power plant department at TÜV SÜD. “The safety systems naturally can’ a safe vane position in stormy weather conditions to prevent damage to the power plant,” explained Drt be affected in any way by the lighting installation.” Following its final approval on Thursday morning, TÜV SÜD gave the green light to putting the installation into operation.
The Siemens Superstar is a mammoth, pioneering technical project. The lighting installation consists of 9,000 light-emitting diodes (LEDs) of the Siemens subsidiary Osram that shine as brightly as 20,000 Christmas candles. In good weather, the art installation can be seen for 30 kilometers. The diameter of the world’s biggest revolving Christmas star is nearly 70 meters – as wide as a soccer field. Nearly 400 meters of power cable were used to install the LEDs – which exceeds the height of the Eifel Tower. The installation weighs about 100 kilos per rotor blade and the lights are attached to the blades with superglue used in space: Under windy conditions, the LEDs are subject to forces up to 20 G, or more than three times the g-force experienced by an astronaut during a rocket launch.
