What is IEC 61000-4-15:2019?

IEC 61000-4-15:2019, also known as "Electromagnetic Compatibility (EMC) - Part 4-15: Testing and Measurement Techniques - Flickermeter - Functional and Design Specifications," is an international standard published by the International Electrotechnical Commission (IEC). It provides specifications for flickermeters used to measure voltage fluctuations in electrical power systems.

Importance of Flicker Measurement

Flicker is a rapid change in light intensity that can occur due to voltage fluctuations. It can cause visual discomfort, affect productivity, and even trigger epileptic seizures in sensitive individuals. Hence, it is crucial to measure and control flicker in electrical systems to ensure user comfort, safety, and compliance with regulatory requirements.

Technical Requirements of IEC 61000-4-15:2019

The IEC 61000-4-15 standard specifies functional and design requirements for flickermeters to ensure accurate and consistent measurements. It covers parameters such as measurement methods, frequency range, measurement uncertainty, dynamic behavior, and environmental conditions for testing.

Testing and Compliance

To comply with IEC 61000-4-15:2019, flickermeters must undergo rigorous testing to verify their performance characteristics. This includes measuring flicker levels under various operating conditions and comparing the results against the standard's defined criteria. Manufacturers need to ensure that their products meet these requirements before they are released into the market.

In conclusion, IEC 61000-4-15:2019 plays a crucial role in ensuring reliable flicker measurement in electrical power systems. By adhering to this standard, manufacturers can provide flickermeters that meet the required specifications, thereby contributing to user comfort and safety. It is essential for professionals working in the field of electromagnetic compatibility (EMC) to have a thorough understanding of this standard and incorporate it into their testing processes.
