Abstract
In this paper, we examine the magnetic properties of 5-leg core for 3-phase transformer, which has a divided structure. Each magnetic property was examined in comparing the magnetic flux density, the magnetic field strength, and the iron loss under the condition of each divided structure mutually. It is known that the iron loss can be expressed by the relationship between the magnetic flux density and the magnetic field strength vector. The two-dimensional vector magnetic properties can be used to express this relationship as a vector. In the analysis, we have used the E&SS modeling, which can express the two-dimensional vector magnetic properties.
