What is IEC 61000-4-28:2018?

IEC 61000-4-28:2018, also known as the International Electrotechnical Commission's (IEC) standard for immunity to voltage dips and short interruptions in public electricity supply systems, provides guidelines and requirements for electrical and electronic equipment. This standard ensures that the equipment can continue to function properly during such power events.

Importance of IEC 61000-4-28:2018

In today's interconnected world, where almost everything relies on electricity, ensuring the proper functioning of electrical and electronic equipment is crucial. Voltage dips and short interruptions can occur due to various reasons like lightning strikes, power grid faults, or switching operations. Such events can disrupt the operation of devices and potentially damage them.

IEC 61000-4-28:2018 helps manufacturers and users of electrical and electronic equipment to ensure that their products can withstand these power disruptions without any adverse effects. Compliance with this standard ensures that devices will continue operating correctly, providing reliable services to users even under less stable power conditions.

Key Requirements of IEC 61000-4-28:2018

This standard specifies the test methods and performance criteria to assess the immunity levels of electrical and electronic equipment against voltage dips, short interruptions, and voltage variations in public electricity supply systems. It sets out the following key requirements:

Test Setup: Defines the test setup, including the test generator, coupling network, and measurement equipment required to perform the tests specified in the standard.

Test Parameters: Specifies the characteristics of voltage dips, short interruptions, and voltage variations, such as duration, frequency, and amplitude.

Performance Criteria: Defines the acceptable performance levels for the tested equipment during and after voltage dips, short interruptions, and voltage variations.

Evaluation and Interpretation of Results: Outlines the procedures for evaluating the impact of power events on the tested equipment and interpret the test results accurately.

Conclusion

IEC 61000-4-28:2018 is a vital standard that ensures the immunity of electrical and electronic equipment to voltage dips and short interruptions in public electricity supply systems. Compliance with this standard provides assurance to manufacturers, users, and consumers that the devices will continue to function correctly even in less stable power conditions. By following the guidelines and requirements specified in IEC 61000-4-28:2018, manufacturers can deliver reliable products, and users can benefit from uninterrupted services.
