摘要
介绍了用于扩增标准电流比的专用电流互感器，可分别将１５０／５、３００／５、６００／５和１２００／５等电流比扩增为１６０／５、３１５／５、６３０／５和１２５０／５等新电流比以及将ｎ／５扩增为ｎ／１新电流比。
A special current transformer used to enlarge the current ratio is introduced in this paper Ratio such as 150/5 A,300/5 A,600/5 A and 1 200/5 A can be enlarged as 160/5 A,315/5 A,630/5 A and 1 250/5 A respectively,also n/5 can be cnlarged as n/1
