摘要
Abstract
With the development of measurement technique and relay protection technology,as well as the digital intelligent instrument and protection equipment widely used,the burden of the current transformers have been decreased.However,until now the manufacturers are still following the traditional design standard,in which the rated capacity is much higher than the actual value.In this paper,the influence of the reduction burden on the current transformer is discussed firstly,and then the rated capacity of current transformer should be reduced is proposed at last.关键词
