Understanding Electromagnetic Compatibility (EMC)

Electromagnetic Compatibility (EMC) is the ability of electrical equipment and systems to function acceptably in their electromagnetic environment, without introducing intolerable electromagnetic disturbances to anything in that environment. The BS EN IEC 61000-3-2:2019+A1:2021 standard specifically addresses the limits for harmonic current emissions, which are critical for ensuring that devices do not interfere with each other or with the power supply.

Why Harmonic Current Emissions Matter

Harmonic currents are a byproduct of non-linear loads in electrical systems, such as those found in computers, televisions, and other electronic devices. These currents can cause a variety of issues, including overheating of equipment, increased losses in the power system, and interference with communication lines. By adhering to the limits set by this standard, manufacturers can ensure that their products do not contribute to these problems, thereby enhancing the reliability and efficiency of the power system.

Who Should Use This Standard?

The BS EN IEC 61000-3-2:2019+A1:2021 standard is indispensable for a wide range of professionals, including:

• Product Designers and Engineers: To ensure that new products meet the necessary EMC requirements.
• Compliance Officers: To verify that products comply with international standards and regulations.
• Quality Assurance Teams: To maintain high standards of product performance and reliability.
• Manufacturers: To ensure that their products are market-ready and meet customer expectations.

Benefits of Compliance

Compliance with the BS EN IEC 61000-3-2:2019+A1:2021 standard offers numerous benefits, including:

• Enhanced Product Performance: Ensures that products operate efficiently without causing interference.
• Market Access: Compliance with international standards is often a prerequisite for entering global markets.
• Customer Satisfaction: Products that meet EMC standards are less likely to experience failures, leading to higher customer satisfaction.
• Reduced Risk of Legal Issues: Adhering to standards helps avoid potential legal challenges related to non-compliance.

Conclusion

The BS EN IEC 61000-3-2:2019+A1:2021 standard is a vital resource for ensuring that electronic devices are compatible with their electromagnetic environment. By setting clear limits for harmonic current emissions, this standard helps manufacturers produce reliable, efficient, and compliant products. Whether you are a designer, engineer, or compliance professional, this standard is an essential tool for achieving excellence in product development and ensuring the smooth operation of electronic systems.

BS EN IEC 61000-3-2:2019+A1:2021

This standard BS EN IEC 61000-3-2:2019+A1:2021 Electromagnetic compatibility (EMC) is classified in these ICS categories:

• 33.100.10 Emission

This part of IEC 61000 deals with the limitation of harmonic currents injected into the public supply system.

It specifies limits of harmonic components of the input current which can be produced by equipment tested under specified conditions.

This part of IEC 61000 is applicable to electrical and electronic equipment having a rated input current up to and including 16 A per phase, and intended to be connected to public low-voltage distribution systems.

Arc welding equipment, which is not professional equipment, with a rated input current up to and including 16 A per phase, is included in the scope of this document. All other arc welding equipment is excluded from the scope of this document; however, the harmonics emission can be evaluated using IEC 61000‑3‑12 and relevant installation restrictions.

The tests according to this document are type tests.

For systems with nominal voltages less than but not equal to 220 V (line-to-neutral), the limits have not yet been considered.

NOTE The words apparatus, appliance, device and equipment are used throughout this document. They have the same meaning for the purposes of this document.
