Pedagogic approaches and sustainable development

The theoretical content of the course is presented through materials available on the learning platform and through lectures. The lectures focus primarily on the analysis of example cases. Studying the theory is closely supported by calculation exercises. The operation of transformers and electrical machines, as well as related measurements, is explored through laboratory work.

The manufacturing and use of transformers and electrical machines are examined from the perspective of sustainable development.

Completion alternatives

No alternative completion methods are available.

Student workload

The course corresponds to 5 ECTS credits and requires approximately 135 hours of student work. Of this workload, around 35–40% consists of contact teaching, while the remaining time is dedicated to independent or group work.
