TM covers the transformer industry, technology and market, but we also cover areas that might have a more pronounced impact on our industry in the future.
Dear readers,
While the domain covered by Transformers Magazine is, naturally, the transformer industry, technology and market, as a reference publication we also cover areas and technologies that may not be extremely important at the moment, but they might have a more pronounced impact on our industry in the near future. One such area is superconductivity. In the past, some transformer manufacturers and other scientific research institutions have made significant investments in superconducting transformers, and a lot of knowledge and experience has been gathered through such scientific research projects. However, due to certain limitations, this technology is still not cost-effective for wider application.
On the other hand, the development of superconducting materials is not slowing down. Today, under certain conditions, superconductors carry 100 to 500 times higher current compared to copper with almost no loss, so it is only a matter of time before we reach the breaking point at which superconducting transformers will become cost-effective. This technology will initially include special application, perhaps in traction transformers or reactors, or maybe in fault-current limiters, aviation, or something else, but nonetheless, the time of superconductivity is slowly but surely coming along.
Five years ago, we published the results of a research project titled Superconducting transformers – Part I and II (Transformers Magazine volume 3, issue 2 and issue 3, 2016), and now, five years later, we wanted to refresh the information in this area. This time, the interest in this topic was considerable, so we gathered a great editorial team led by Dr. Mohammad Yazdani Asrami, Deputy Editor-in-Chief for this edition, and an excellent line-up of authors that helped us prepare an entire edition dedicated to superconductivity.
Considering the wider importance of this technology, we have not limited ourselves to topics related to transformers and reactors, but have, nevertheless, included fault current limiters, cables and superconducting materials.
I am extremely grateful to all editors, reviewers, and authors for taking part in this edition which abounds in top quality materials. In the hope that you will find the information we bring to you useful, I wish you a joyful reading!
