低压电流互感器的选择

Simply analyse the choice of the mutual inductor of low-voltage current transformer

针对现低压互感器普遍存在指示过小的现象,对低压电流互感器的二次负荷、准确度等级及负载能力等技术参数进行分析,提出了不同情况下选择低压电流互感器的变比时需注意的问题.

To the phenomenon that the instruct of low -voltage current transformer is too little, such technical parameters as sencondarly load, the class of accuracy and load ability to the current transformer, are analysed. We must pay attention to the question that choose the former under different situation.
