Title: What is the Test Standard EN 61000-3-2:2014? A Comprehensive Guide

The world we live in is becoming increasingly digital and reliant on technology. As a result, the demand for high-quality power supplies has increased, and the need for regulations that govern the use of electronic devices has become more critical. One such standard is the IEC 61000-3-2, also known as "Electromagnetic compatibility (EMC) - Part 3-2: Limits - Limits for harmonic currents produced by equipment connected to public low-voltage systems with input current >16A and 16A and <= 75 A per phase, " is an international standard that specifies the limits for harmonic current emissions in electrical power systems.

The Limits in the Test Standard

The EN 61000-3-2 standard is divided into four parts. The first part, "Electromagnetic compatibility (EMC) - Part 3-2: Limits, " sets the limits for electromagnetic interference (EMI) and radio frequency interference (RFI) in electrical equipment. The second part, "Electromagnetic compatibility (EMC) - Part 3-2: Limits - Limits for harmonic currents, " sets the limits for harmonic current emissions in electrical power systems.

The third part, "Electromagnetic compatibility (EMC) - Part 3-2: Limits - Limits for current-carrying structures, " sets the limits for current-carrying structures, such as transformers and generators, in electrical equipment.

The fourth part, "Electromagnetic compatibility (EMC) - Part 3-2: Limits - Limits for power-supply equipment, " sets the limits for power-supply equipment, such as switchboards and fuses.

The Significance of EN 61000-3-2

The EN 61000-3-2 standard is crucial for ensuring the quality of electrical power systems. The limits set by the standard are designed to prevent equipment from producing excessive harmonic currents, which can cause damage to the equipment and disrupt the power supply.

The EN 61000-3-2 standard is also important for protecting public safety in cases where equipment may pose a risk to electrical shock or other injuries. By establishing limits for harmonic current emissions, the standard helps to reduce the risk of electrical accidents and incidents.

Historical Background

The development of the EN 61000-3-2 standard can be traced back to the 1980s, when the European Community began to regulate electromagnetic compatibility (EMC) in order to protect consumers and the environment.

The standard was first published in 2014, and it has since been updated several times to reflect new developments in the field. The 2014 version of the standard is the latest version, and it has undergone significant revisions since its initial publication.

Conclusion

The EN 61000-3-2 standard is an essential tool for ensuring the quality of electrical power systems and protecting public safety. By establishing limits for harmonic current emissions, the standard helps to prevent equipment from producing excessive current, which can cause damage to the equipment and disrupt the power supply.

We hope this article has provided a comprehensive understanding of the EN 61000-3-2 standard and its implications.
