According to the 10% error curve check current transformer accuracy
Teng Hong-jiang · Hunan Agricultural Machinery · 2012
According to the 10% error curve calibration accuracy of current transformer is,as long as the Zf or m value does not exceed the curve determined by the allowable value,error of current transformer in the allowed range.Comparison of calculated value(or measurement) Zf and allowable values of Zfm,if Zf Zfm,can determine the current transformer maximum current error is less than 10%,meet the standard requirement;and do not accord with.
