The authors present the changes in IEEE STD 519-1981, titled IEEE Guide for Harmonic Control and Reactive Compensation of Static Power Converters, that are to be made in 1988 as the result of a two-year review. The voltage distortion criteria in the 1981 edition could not be used to distribute among users, the ability of the utility system to absorb harmonic currents. This problem is addressed in the revision. There are now two criteria that are used to evaluate harmonic distortion. The first is a limitation in the harmonic current that a user can transmit into the utility system. The second criterion is the quality of the voltage that the utility must furnish the user. Examples of the application of the revised standard, which has been upgraded to a Recommended Practice, are given.>
