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 document establishes specific technical requirements concerning electromagnetic compatibility within electrical networks. It addresses phenomena including voltage variation, voltage fluctuation, and flicker generated by electrical apparatus connected to public low-voltage distribution systems. The scope specifically targets devices rated at a phase current not exceeding 16 amperes that do not necessitate special connection provisions. The text defines permissible limits for these electrical disturbances to ensure compatibility between connected equipment and the power supply grid. By adhering to these criteria, manufacturers and users can mitigate potential interference effects on the stability of the electrical environment. The guidelines apply to household and similar applications within the specified current rating. Implementation of these provisions aims to maintain power quality and prevent adverse effects on other connected devices. The standards provide a framework for testing and compliance assessment related to flicker and voltage stability in low-voltage installations.
