DEHN protects wind turbines

Reliabledetection of long stroke currents in wind turbines with DEHNdetect

Avoidexpensive maintenance and long downtime.

Theproblem: as it does not necessarily lead to the immediate failure of thesystem, damage caused by lightning often remains undetected in wind turbines.Initial long stroke current of only a few 100 A is frequently the chief causeof damage, e.g., melting on the receptors of the rotor blades. In the longterm, this damage can lead to system failure.

WithDEHNdetect you can keep an eye on all the parameters of a lightning event.

Decisionsabout repair jobs or servicing work are then based on detailed informationrather than gut instinct.

DEHN TestCentre

Our testcentre with a floor space of 800 m2 is equipped with the latest devices andtechnologies. This allows us to perform lightning current tests on products,installations and systems. Of course, the tests performed in our test centreare based on the relevant standards. Thanks to our active involvement withinternational and national standardisation committees, we are alwaysup-to-date.

Ourlightning impulse current laboratory is able to generate lightning currentswith a peak value up to 400 kA (10/350 µs). It is one of the most powerful ofits kind in the world.
