What is IEC 61000-4-24:2015-AMD1:2018?

The International Electrotechnical Commission (IEC) develops and publishes standards for electrical and electronic technologies. One of the key standards specific to electromagnetic compatibility (EMC) is IEC 61000-4-24. This article aims to explore the significance and details of IEC 61000-4-24:2015-AMD1:2018.

Understanding IEC 61000-4-24

IEC 61000-4-24, titled "Electromagnetic compatibility (EMC) - Part 4-24: Testing and measurement techniques - Test methods for immunity to power disturbances in low-voltage power supply systems," specifies a series of test methods to determine the immunity of electrical and electronic equipment operating in the frequency range of the rated supply voltage from disturbances caused by voltage dips, short interruptions, and voltage variations.

This standard defines the necessary criteria to ensure the proper functioning of electrical equipment in the presence of power disturbances. It sets out various test configurations, test levels, and measurement techniques to assess the immunity of equipment against power quality issues. Compliance with IEC 61000-4-24 ensures that devices can operate without disruption or damage when exposed to power disturbances that commonly occur in low-voltage power supply systems.

Key Updates in IEC 61000-4-24:2015-AMD1:2018

IEC periodically updates its standards to incorporate technological advancements and address emerging challenges. The amendment 1 introduced in 2018 includes important updates to IEC 61000-4-24:2015.

The amendment features revised requirements for the pulse duration and rise time of voltage dips, as well as changes to the test severity levels. Additionally, it provides testing guidance for equipment with variable sensitivity or different performance requirements. These updates improve the accuracy and applicability of the standard, ensuring that equipment can withstand a wider range of power disturbances.

Conclusion

IEC 61000-4-24:2015-AMD1:2018 plays a critical role in ensuring the reliability and robustness of electrical and electronic equipment operating in low-voltage power supply systems. By following the test methods and criteria outlined in the standard, manufacturers and users can assess the immunity of their devices against voltage dips, short interruptions, and voltage variations. Compliance with this standard helps minimize disruptions caused by power quality issues and promotes the seamless operation of equipment in various environments.
