MotorDoc Vlog 75 A Discussion of IEEE Std 43 2022 the IEEE Standard for Harmonic Control

IEEE Std 519™-2022 is a technical standard providing guidance for controlling electrical harmonics in power systems, establishing design goals for systems with both linear and nonlinear loads by defining acceptable voltage and current waveform distortion at the point of common coupling between the utility and the user. It details measurement techniques and sets specific limits for different voltage levels, acknowledging the shared responsibility between utilities and users for managing harmonic distortion. The accompanying article, “How Misapplying IEEE 519 Affects Inverters and Harmonic Distortion,” discusses the practical application of this standard, highlighting that the limits apply to the facility’s connection point with the grid, not individual pieces of equipment like variable frequency drives, and exploring the detrimental effects of harmonic distortion, particularly current distortion, on electrical machinery and overall system efficiency. Both sources emphasize the importance of adhering to harmonic limits to prevent equipment damage, reduce energy losses, and ensure reliable power system operation.
