IEEE 519 and what does it govern?

• A. IEEE 519 defines arc-flash PPE requirements.
• B. IEEE 519 sets standards for grounding electrode conductors.
• C. IEEE 519 establishes recommended practices for harmonic control in electrical power systems.
• D. IEEE 519 outlines grounding of audio equipment.

Answer: (C)

Harmonics and power quality control in electrical systems. IEEE 519 sets the recommended practices and limits for harmonic control, specifying how much harmonic current and voltage distortion is acceptable at various points in a power system and near equipment. This guides designers and operators to limit distortion, prevent overheating, misoperation of protection, and resonance, and to choose appropriate mitigation measures such as filters, impedance planning, and proper sourcing of nonlinear loads. The goal is coordinated action between utilities and customers to keep overall power quality within agreed limits. Other items are governed by different standards: arc-flash PPE requirements come from standards like NFPA 70E (and arc-flash analysis standards such as IEEE 1584); grounding electrode conductors and system grounding are covered by separate guidelines (e.g., IEEE 142 and related codes); grounding of audio equipment isn’t within the focus of IEEE 519.
