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 part of IEC 61000 is concerned with the limitation of voltage fluctuations and flicker impressed on the public low-voltage system. It specifies limits of voltage changes which may be produced by an equipment tested under specified conditions and gives guidance on methods of assessment. This part of IEC 61000 is applicable to electrical and electronic equipment having an input current equal to or less than 16 A per phase, intended to be connected to public low-voltage distribution systems of between 220 V and 250 V line to neutral at 50 Hz, and not subject to conditional connection. Equipment which does not comply with the limits of this part of IEC 61000 when tested with the reference impedance Zref of 6.4, and which therefore cannot be declared compliant with this part, may be retested or evaluated to show conformity with IEC 61000-3-11. Part 3-11 is applicable to equipment with rated input current ≤ 75 A per phase and subject to conditional connection. The tests according to this part are type tests. Particular test conditions are given in Annex A and the test circuit is shown in Figure 1.

Ta del standarda IEC 61000 obravnava omejitev vrednosti kolebanja napetosti in flikerja v javnih nizkonapetostnih napajalnih sistemih. Določa omejitve vrednosti kolebanja napetosti, ki jih lahko proizvede oprema, preizkušena pod določenimi pogoji, in podaja smernice za metode ocenjevanja. Ta del standarda IEC 61000 se uporablja za električno in elektronsko opremo z vhodnim tokom do vključno 16 A na fazo, ki je namenjena za povezavo z javnimi nizkonapetostnimi razdelilnimi sistemi z napetostjo med linijskim in nevtralnim vodnikom od 220 V do 250 V pri 50 Hz ter ni priključena pod posebnimi pogoji. Če opremo, ki ni v skladu z omejitvami tega dela standarda IEC 61000, preskušate z referenčno impedanco Zref 6,4 in je zato ni mogoče razglasiti za skladno s tem delom, jo lahko znova preskusite oziroma ocenite, ali je skladna s standardom IEC 61000-3-11. Del 3-11 se uporablja za opremo z nazivnim vhodnim tokom ≤ 75 A na fazo in je priključena pod posebnimi pogoji. Preskusi po tem delu so tipski preskusi. Posebni preskusni pogoji so navedeni v dodatku A, preskusni krog pa je prikazan na sliki 1.

Overview
SIST EN 61000-3-3:2014/A1:2019 addresses essential aspects of electromagnetic compatibility (EMC) by specifying the limits for voltage changes, voltage fluctuations, and flicker in public low-voltage supply systems. This standard applies specifically to electrical and electronic equipment with a rated input current of 16 A or less per phase and designed for connection to public low-voltage distribution systems (220-250 V, 50 Hz, line to neutral) without conditional connection requirements.
The purpose of the standard is to protect the stability and quality of public power supply systems by limiting electrical disturbances, ensuring reliable operation and user comfort within residential and commercial environments.
Key Topics
- Voltage Fluctuation and Flicker Limits: Defines permissible levels for voltage changes and flicker produced by electrical equipment under defined test conditions.
- Scope and Applicability: Covers equipment with a rated current ≤ 16 A per phase that connects directly to public low-voltage networks and is not subjected to conditional connection.
- Type Testing Requirements: Sets out type test protocols and test circuit details, including reference impedance, to standardize compliance assessment.
- Equipment Categories: Addresses equipment with manual and automatic switching, multiple separately controlled circuits, and specific categories such as lighting equipment and hotplates.
- Guidance for Non-Compliant Equipment: Outlines procedures for retesting and possible reference to IEC 61000-3-11 for equipment exceeding specified limits, accommodating higher input currents up to 75 A under conditional connection.
Applications
The requirements of SIST EN 61000-3-3:2014/A1:2019 are crucial for:
- Manufacturers and Designers: Ensuring electrical and electronic products meet EMC compliance for connection to European low-voltage public supply systems.
- Product Testing Laboratories: Performing standardized type tests to demonstrate conformity with EMC regulations.
- Product Certification: Documenting compliance with essential EMC requirements for CE marking under the EU’s Directive 2014/30/EU.
- Lighting and Appliance Industries: Assessing the flicker and voltage fluctuation emissions of luminaires, household hotplates, and similar devices.
- Market Access: Facilitating legal and unhindered entry of compliant equipment into the European market.
The implementation of this standard is integral to maintaining high power quality, minimizing the risk of nuisance voltage variations, and preventing customer complaints related to visible flicker in lighting.
