Due to the development of CAE technical and computer technology in recent years, many analyses and reports have been using three-dimensional models of transformers. However, analyses have been difficult to perform within a practical amount of calculation time, and have been simplified to partial models.
This paper describes an example in which the three-dimensional magnetic field analysis of a large-scale transformer is performed at a real scale level via parallel calculation processing using an actual PC held in our company. The utility of the process of parallelization is evaluated also.
