EN 61000-3-2:2020, also known as the European Standard for Electromagnetic Compatibility (EMC) - Part 3-2, sets forth the limits for harmonic currents produced by equipment with an input current up to and including 16 A per phase. The standard specifies the maximum limits of harmonic emissions that electrical equipment can produce when connected to the public low-voltage supply system.
Importance of EN 61000-3-2:2020
The harmonics generated by electrical devices have a negative impact on power quality and can greatly affect the performance of the electrical grid. These harmonics often cause excessive heating in electrical conductors, transformers, and other equipment, leading to increased energy losses and reduced overall efficiency. Additionally, harmonics can interfere with communication systems, causing disruptions and affecting the operation of sensitive electronic devices. Implementing EN 61000-3-2:2020 helps ensure the proper functioning of electrical equipment while minimizing undesirable effects on the electrical system.
Requirements of EN 61000-3-2:2020
The standard defines the requirements for equipment based on its power rating and category. It states the maximum allowable harmonic current emissions at different frequencies and provides methods for measuring and testing these emissions. Equipment manufacturers must comply with these requirements to obtain the necessary certification, demonstrating their products' compliance with the EMC standards.
EN 61000-3-2:2020 requires that electrical equipment meets certain power factor and Total Harmonic Distortion (THD) limits to minimize harmonic current injection into the power supply. It specifies how measurements should be performed and provides guidance on complying with THD limits based on different product categories.
Benefits of EN 61000-3-2:2020 Compliance
Complying with EN 61000-3-2:2020 not only ensures that electrical equipment operates efficiently and without causing disturbances in the power grid but also provides various other benefits. Firstly, it helps reduce energy losses, leading to improved energy efficiency and lower operating costs. Secondly, by limiting harmonic emissions, equipment manufacturers contribute to a greener environment by reducing their products' negative impact on electrical systems. Lastly, compliance with EMC standards enhances the reputation and reliability of manufacturers, as customers gain confidence in the quality and safety of their products.
In conclusion, EN 61000-3-2:2020 is a crucial standard that sets limits for harmonic currents generated by electrical equipment. Compliance with this standard is essential for maintaining the proper functioning of the power grid and ensuring the efficient operation of electrical devices. By adhering to EN 61000-3-2:2020, manufacturers can meet regulatory requirements, improve energy efficiency, and enhance their reputation in the market.
