Webcommon design of CCVT provide many benefits, these CCVT's do not provide the linear, flat frequency response required to accurately measure harmonic voltage distortions across the most critical range of the harmonic frequency spectrums, thus requiring in the field calibration [1] that may have an adverse effect on the accuracy of the measurement. WebIf you are using a CVT of 1% accuracy class, maximum acceptable voltage unbalance is 1%. (I know IEC61000-3-13 is another standard related to unbalance, but unfortunately I don't have access to it ... red lake victims
