Revisions to IEEE Standard 519-1992

IEEE Standard 519-1992 is nearing the final stages of a revision. The major goals of this revision are to incorporate experience gained since 1992 and to further harmonize with other standards in this field, notably IEC Std. 61000-3-6. The major areas of revision which have been identified, drafted, and reviewed are summarized in this paper. These include the addition of harmonic voltage limits for point-of-common coupling locations with a rated voltage of less than 1.0 kV, the adoption of the harmonic measurement protocols of IEC Standard 61000-4-7, the inclusion of interharmonic limits, and the incorporation of statistical methods to capture time-varying aspects of harmonics in a way consistent with IEC Standard 61000-3-6. Additional topics which have been proposed as a result of the initial review process are also presented
