Editorial message

I strongly believe that it is this unbridled optimism and the zeal that could not have gone unnoticed while we were preparing the materials for this issue of Transformers Magazine that have marked this editio

Editorial Message

Investments in power grids worth billions are being announced, and there is a presence of high optimism at fairs and conferences. In short, this is the climate we have been anticipating for years

Editorial message

The recent surge in global commodity prices is probably the most discussed business topic at the moment. In several instances, raw material prices have doubled over the past year. Clearly, this has created great challenges for the sustainable manufacturing business and caused some transformer manufacturers to publicly announce price increases. Transformers Magazine has previously published educational materials on supply chain management and I would like to take this opportunity to jog your memory about the articles written by Ufuk Kivrak - \u27Creating value through supplier relations management and strategic partnerships\u27, published in volume 7 (2020), issue 4, and \u27Supply chain management\u27, published in the Special Edition on Substations in 2019, in which you can find very useful recommendations on how to reduce the risks of rising raw material prices

Editorial message

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! Mladen Banović, Editor-in-Chie
