摘要
从磁通势和感应电动势的角度阐述了电流互感器的减极性含义,绘制的电流互感器相量图消除了二次电流方向与实际工况明显相反的弊端。相关的概念、分析方法适用于电压互感器、变压器的原理分析。
This paper explains the subtractive polarity meaning of the current transformer from the point of magneto motive force and electromotive force （EMF）. Drawn phasor diagram eliminates the drawback of secondary current direc tion in contrast with the actual condition. Related concepts and analytical methods are adaptive to the voltage transform ers and the transformers.
