Introduction(This introduction is not part of IEEE P1495, Guide on Harmonic Limits for Single-Phase Equipment.) With increasing quantities of non-linear loads being added to electrical systems, it has become necessary to establish criteria for limiting problems from system voltage degradation. Presently, IEEE Standard 519-1992 addresses harmonic limits at the consumer and service provider interface. The intent of IEEE 519 is to limit harmonic current injection into power systems and ensure voltage integrity. This standard is manageable and practical when properly applied to industrial and commercial three-phase consumers. However, when IEEE 519 is applied to single-phase system connections (particularly residential consumers), it can become highly impractical. Furthermore, engineering studies indicate that the cumulative effect of single-phase non-linear loads may potentially cause voltage degradation on power distribution systems even with individual single-phase consumer IEEE 519 compliance. The following guide At the time this standard was completed, the working group had the following membership: The following persons were on the balloting committee: (To be provided by IEEE editor at time of publication.)
