TRAMAG Low Harmonic Filter (LHF) Chokes for trouble-free operation of Island-Power-Supplies
Highlight of the week
Separated from the public interconnected power grids operated by large energy supply companies, technologically complex drives and automation systems in so-called island grids can also be supplied with electrical energy without interference, which is usually generated by power-adapted generators.
“Ready for the island” – a German saying for need of a break or holiday – this is how our TRAMAG-LHF-chokes could be described in this context, which are used, for example, in generator-operated island grids for maritime shipping.
Individual solutions from our TRAMAG specialists
Connected upstream of the converter, which among other things electrically controls the motors for ship rudder systems, the LHF choke ensures the required power quality by reducing undesired mains feedback. It thus protects consumers connected in parallel and the generator itself from disturbing and damaging harmonics in the stand-alone mains. The TRAMAG-LHF choke, which has been specially designed for this purpose, ensures that the so-called THDi (Total Harmonic Distortion of Current) value remains below 10%, thus keeping the superimposition of the sine wave fundamental oscillation as low as possible.
For years, customers all over the world have trusted in TRAMAG’s solution competence for the use of transformers, chokes and filters for a wide variety of electrotechnical applications, including the trouble-free operation of island power supplies.
This also includes local grids that are operated with regenerative energy generation, e.g. from photovoltaic systems. For these applications, too, our employees in sales, development and production use their experience, knowledge and work to ensure stable power quality and thus a safe power supply with transformers, chokes and filters from TRAMAG.
We look forward to your request.

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.
