Which standard provides guidance on harmonic control in electrical power systems?

• A. IEEE 1584
• B. IEEE 519
• C. NFPA 70
• D. IEC 60364

Answer: (B)

Guidance on harmonic control in electrical power systems is provided by IEEE 519. This standard lays out the recommended limits for harmonic voltage and current distortion at the point of common coupling and offers practical ways to mitigate harmonics. It covers how to measure harmonics, set acceptable levels for nonlinear loads, and implement strategies such as filters, proper transformer sizing, and impedance considerations to keep power quality within limits. In contrast, the other standards focus on different areas: IEEE 1584 deals with arc-flash hazards, NFPA 70 is the electrical safety code for installations, and IEC 60364 covers general electrical installation design. So IEEE 519 is the one that specifically addresses harmonic control.
