| 摘 要： | 保护用电流互感器(TA)性能的基本要求是在规定使用条件下的误差应在规定限度内,而应用中的突出问题是系统故障时通过短路电流引起铁心饱和,导致励磁电流显著增加而加大了互感器的传变误差。因此在工程设计中选用TA时,需要采取恰当的措施来减轻TA饱和的影响。

| Abstract: | The characteristic basic demand of protection current transformer(TA) is that under the prescribed using condition,the error should be in the fixed limitation.But the obvious question is that short-circuit current makes iron core saturated at the same time current increase largely,and finally makes the error of transfer more large.So if we use TA in project design,we should take measures to relieve the influence of TA saturation. |
