The traditional theory of tap change of the load-ratiotransformer which has not taken the ferromagnetic characteristic into account is a special example of the theory presented in this paper.
在变压器铁磁特性不明显的情况下推导出的传统有载调压变压器无暂态切换理论只是文中理论中的一个特例。

The voltage ratio is one of important parameters of transformer .
牵引变压器的选择是人们长期关心的问题之一。
