In transformer design, it is essential to study loss using magnetic field analysis. In recent years, three-dimensional magnetic field analysis for large power transformers has also become possible in practical time. We introduced an example of them in JMAG Users Conference 2019.
In this presentation, an example of three-dimensional magnetic field analysis of large power transformers using transient analysis is introduced, where the following topics are described: the condition of transient analysis, the comparison between results using frequency response and transient analysis, and the computation time when using parallel computing.
