Dear Readers,

Not long ago, a book related to transformers came to my hands, with one of the opening remarks stating that to date, fundamental transformer technology hasn’t seen a significant change since transformers were first invented more than a century ago. Although this type of a statement is something that we hear and read about regularly in conference papers etc., this time it made me think about the things that have changed about transformers since their first days, and those that remained the same.

This year we are marking the 100th anniversary of IEEE Transformers Committee. This jubilee was celebrated at the Spring Meeting in Pittsburgh, USA in March, where we could learn more about the number of standards the committee has produced over the century, and see historical photos of transformers displayed on posters and in the brochure the committee prepared for this occasion. All of this again made me think about the statement from the beginning of this editorial.

Comparing visually those first transformers to today’s modern transformers (for example, 1,100 kV DC transformers, see Transformers Magazine Vol. 5, Issue 1, p. 8), a dramatic evolution of technology can be seen.
