On the basis of the analysis of static economic load rate, a dynamic optimal economic load rate of transformer is provided, which is the basis for selection of trans-former capacity.
并在变压器静态经济负载率分析的基础上提出变压器动态最佳负载率，以此作为变压器经济容量的选择依据。

This lack of static, DC offset current in the output transformer means that the core can be made smaller, because it requires no air gap to prevent core saturation from the static DC offset current.
