| Abstract: | 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. |
