摘要
目前,国内外对大电流互感器屏蔽绕组电流的计算还没有一个准确的计算公式,笔者用有限元法计算了屏蔽绕组中的电流,对仿真的结果和试验数据进行的比较说明,仿真结果是可靠的。
At present, calculation of current in shielding windings of large current transformer under testing condition doesn't have accurate formula yet in the word. In this paper, the current is calculated by finite element method. The results are proved to be reliable, compared with the testing results of large current transformer.
