What is IEC 61000-4-135:2019?

IEC 61000-4-135:2019, entitled "Electromagnetic compatibility (EMC) - Part 4-135: Testing and measurement techniques - Power quality measurement methods for mains power supply systems connected to the telecommunications network," is an international standard that specifies the requirements and guidelines for measuring and assessing power quality in electrical systems connected to telecommunications networks. It provides a framework for evaluating the impact of electromagnetic disturbances on the quality of power supply.

The Importance of Power Quality

In today's digital age, where telecommunication networks are essential for communication and data transmission, maintaining high-quality power supply becomes crucial. Poor power quality can lead to various issues, including disruptions in communication, damage to electronic equipment, and reduced system performance. IEC 61000-4-135:2019 aims to address these concerns by providing standardized methods for measuring, evaluating, and improving power quality.

Testing and Measurement Techniques

IEC 61000-4-135:2019 presents a detailed set of testing and measurement techniques to assess power quality parameters. These techniques involve capturing and analyzing relevant electrical parameters such as voltage variations, frequency deviations, harmonics, interharmonics, and voltage dips/interruptions. The standard outlines the necessary equipment, measurement procedures, and reporting requirements to ensure accurate and consistent assessments.

Compliance and Implementation

IEC 61000-4-135:2019 serves as a reference for manufacturers, regulators, and users of electrical and telecommunications equipment. Compliance with this standard helps ensure the compatibility and interoperability of devices operating within the same network. By implementing the recommended measurement methods and thresholds, stakeholders can identify power quality issues, take necessary corrective actions, and verify the effectiveness of mitigation measures.
