AC Loss of the Double Pancake Winding by External Field

외부자계 인가시 더블팬케이크 권선에서 발생하는 교류손실

Magnetization loss which is generated in HTS wire varies with the direction of the external magnetic field. This paper calculates the magnetization loss in an HTS transformer winding, where effects of the direction of magnetic field are considered. Kim model is used to consider the variation of the critical current with magnetic field and Brandt equation is used to calculate the loss by perpendicular magnetic field in transformer winding. Magnetization loss in an HTS transformer can be calculated more precisely with this paper.
