Electromagnetic compatibility (EMC) - Part 3-3: Limits - Limitation of voltage changes, voltage fluctuations and flicker in public low-voltage supply systems, for equipment with rated current <= 16 A per phase and not subject to conditional connection

This technical document outlines specific requirements concerning electromagnetic compatibility for electrical and electronic equipment connected to public low-voltage power supply systems. It establishes permissible limits for voltage changes, voltage fluctuations, and flicker for devices with a rated phase current not exceeding 16 amperes that do not require special connection conditions. The scope covers equipment intended for household, commercial, and light industrial use, ensuring that the operation of such devices does not adversely affect the power supply network or interfere with the performance of other connected loads. Detailed methodologies for testing equipment behavior under these constraints are provided to assess compliance with the established thresholds. The provisions address the technical measures necessary to maintain power quality and system stability within defined boundaries. This specification aligns with broader international frameworks for managing electromagnetic disturbances and ensures that products meet the expected performance criteria regarding their impact on the electrical grid. Adherence to these guidelines facilitates the interoperability of equipment across different markets and supports the overall reliability of the power distribution infrastructure.
