| Abstract: | The metering error will occur when current transformer does not operate in rating condition.Based on a real case in which the improper configuration of metering current transformer and load causes the increase of metering loss,the feature curve of metering current transformer is analyzed,the principle of rational configuration of metering transformer and load is described,and specific solution is presented. |
