What is IEC TR 61000-4-19:2019?

IEC TR 61000-4-19:2019 is a technical report published by the International Electrotechnical Commission (IEC). It provides guidance and recommendations for measuring and assessing power quality parameters associated with voltage fluctuation and flicker. This standard focuses on the impact of these disturbances on sensitive electrical and electronic equipment, aiming to ensure their proper functioning and minimize any negative effects.

Main Features of IEC TR 61000-4-19:2019

The primary objective of IEC TR 61000-4-19:2019 is to establish a unified approach for assessing voltage fluctuations and flicker in electrical systems. The technical report defines specific measurement methods and evaluation criteria to quantify these disturbances accurately. It provides guidelines on how to measure flicker severity, taking into account the characteristics of different equipment and the potential impact on human perception.

One significant feature of this standard is that it takes both short-term and long-term voltage variations into consideration. Voltage fluctuations, which occur over short periods, can result from rapid changes in electrical loads or intermittent disturbances. Long-term voltage variations, on the other hand, may be caused by power system operation, load variations, or grid faults. The technical report offers guidance on evaluating and interpreting the severity of these fluctuations based on standardized metrics.

Importance and Application Areas

IEC TR 61000-4-19:2019 plays a crucial role in ensuring the reliable operation of sensitive electrical and electronic devices. Any form of voltage fluctuation or flicker can have detrimental effects on equipment performance, leading to malfunctions, data corruption, or even safety hazards. By following the recommended measurement and assessment techniques outlined in the standard, manufacturers, system operators, and users can evaluate their equipment's vulnerability to these disturbances. They can then take appropriate actions to mitigate potential risks.

This technical report finds application in various sectors where power quality is of utmost importance. Industries such as manufacturing, healthcare, telecommunications, and transportation heavily rely on high-quality power supply to maintain uninterrupted operations. Other areas, including renewable energy systems, process control, and research facilities, also benefit from adhering to the guidelines set forth by IEC TR 61000-4-19:2019.

Conclusion

IEC TR 61000-4-19:2019 provides valuable guidance for measuring and evaluating voltage fluctuation and flicker in electrical systems. By following this technical report, stakeholders can ensure the proper functioning of sensitive equipment and minimize any adverse effects caused by these disturbances. Implementing the recommendations outlined in this standard will contribute to a higher level of power quality, enhancing operational efficiency, and reducing equipment downtime across various industries.
