TRAMAG Filter Chokes for Wind Turbines in use for Clean Energy Transition

Newly installed onshore wind turbines in Germany (as of 2021) with a hub height of Ø 140m and a rotor blade diameter of Ø 133m generate an Ø output of about 4 MW in optimal wind conditions. This can supply Ø 3,000 to 4,000 households with electricity. These wind turbines are exposed to extreme loads during operation. The requirements regarding efficiency/yield, safety, corrosion resistance, stability and durability, also for the electrical components used in the nacelle, are correspondingly high.

The main components of the wind turbine are the rotor with blades and, in the nacelle, the mechanical drive train and the electricity-producing wind turbine generator. In the electrical regulation and control system, which is responsible for the efficient operation of the turbine, a specially developed TRAMAG filter choke performs its service reliably.

Our filter choke, functionally designed like a du/dt filter, is designed for particularly high current linearity and overload capacity. It is also characterized by very low tolerance values of the rated inductance Lrat per phase. This is achieved by a “five-leg choke type” specially developed by TRAMAG for this application.

TRAMAG: We make it possible

Adverse climatic conditions, often caused by installation sites close to the sea, require an additional surface treatment which ensures that the filter choke is “salt spray resistant” during operation. In addition, the choke is technically optimized for the small nacelle installation space: With low losses and a compact design, well equipped for the special mechanical and thermal requirements.

For years, customers all over the world have relied on our TRAMAG solutions expertise in transformers, chokes and filters for reliable use in renewable energy generation with wind turbines for a climate-neutral electricity supply.

Quality is when your QMB goes “High-Five-S” with you

We know where quality must ultimately be demonstrated and proven: In the product, in the customer’s application. But where does quality begin? On the one hand in technical development and on the other hand in the organization of workplaces in production. Employees who keep their workstations tidy maintain an overview, have access to the right tools at all times and can work on the product efficiently and with quality assurance.

Information visit to TRAMAG by the VDI District Association of Bavaria North-East

On the afternoon of St Nicholas’ Day, the TRAMAG plant in Fürth hosted an information event for members of the Association of German Engineers (VDI) from the Bavarian North-East District Association. Due to the regional proximity and also taking TRAMAG’s 100th anniversary as an occasion, we received a request from the Nuremberg VDI local group to visit our plant, which we were very happy to fulfil.

“Quality is when the Customer comes back and not the Product”

The most technically innovative or economically attractive product in an application is worth nothing if the quality is not right. Not only would the failure of the product itself have to be lamented, but possibly also further damage to the entire application.
