Course - Transformer Design - ET8104
ET8104 - Transformer Design
Lessons are not given in the academic year 2021/2022
The course is an in depth study of selected topics about power transformers. In more detail, the content of the course is: - Basic transformer theory. Equivalent circuit. Dimensional analysis. - Transformer construction and fabrication. This includes transformer core and windings. Use and design of different type of cores and windings. - Materials - use and properties(core, insluation, cooling, supporting parts). Historical development. - Reactances, forces - Surge phenomena (short circuit, impulse voltages, inrush phenomena) - Cooling - thermal analysis - Testing - Operation
Knowledge: After completing the course, the student shall: - understand transformer design. - understand principles for operation of transformers. - be able to develop futher tailor made transformer models of e.g. core losses. - have knowledge about materials used in core, windings, insulation and cooling. - understand principles for transformer testing. - understand the relationship between requirements and design implementation. - understand factors driving modern day development and optimization, based on knowledge about the historical development. Skills: After completing the course, the student shall be able to: - develop tools for design calculation and parameter calculation for transformers. - develop tailored models for analysis of surge phenomena. - specify, test and operate power transformers.
Learning methods and activities
The teaching is based on a colloquium approach, where each topic is briefly presented before a more detailed discussion takes place. All participants must prepare before the weekly colloquium. The course will be given in English if necessary. The course is given every second year, next time spring 2021.
