Rapid design is one of the main imperatives of modern manufacturing, following from the principles of mechatronics. In the ever-important electrical power industry, transformers play one of the most important roles, both from the point of view of energy savings and reliability of the whole system. Though basic methods of computation of almost all main parts of power transformers have been well known for many years, the 3-D stray field phenomenon continues to be studied. In this article a review of many years of research and co-operation with national and foreign industries is presented. Effective and experimentally verified methods are reported.

Szybkie projektowanie jest jednym z głównych imperatywów nowoczesnej produkcji, opartej na zasadach mechatroniki. W zawsze ważnym przemyśle elektroenergetycznym transformatory odgrywają szczególną rolą, zarówno z punktu widzenia oszczędności energii jak i niezawodności całych systemów. Chociaż podstawowe metody obliczeń prawie wszystkich głównych części są opanowane od wielu lat, to zjawiska rozproszeniowe w polach trójwymiarowych są wciąż jeszcze badane. W pracy podano przegląd wyników wieloletnich badań i współpracy z przemysłem krajowym i zagranicznym. Zaproponowano potwierdzone eksperymentalnie efektywne metody.
