Overview
EN 61000-4-34:2007/A2:2025 is a European standard established by CLC and aligned with IEC 61000-4-34:2005/AMD2:2025. It focuses on electromagnetic compatibility (EMC), specifically addressing testing and measurement techniques related to the immunity of electrical equipment to voltage disturbances. This amendment updates the testing procedures for equipment that operates with a mains current exceeding 16 A per phase.
The standard is crucial for manufacturers, testing laboratories, and certification bodies involved in assessing how robust electrical and electronic equipment is when subjected to voltage dips, short interruptions, and voltage variations in the supply network. It supports maintaining equipment reliability and performance under real-world conditions and power quality issues.
Key Topics
Voltage Dips and Short Interruptions Immunity
The standard defines methods for testing equipment immunity to unexpected reductions and short interruptions in supply voltage. These disturbances are common in power networks and can impact device operation.Voltage Variations Immunity
Procedures and measurement techniques assess equipment response to voltage fluctuations exceeding normal operating ranges.High Current Equipment Focus
Targets devices drawing more than 16 A per phase from the mains, including industrial equipment, heavy machinery, and certain consumer appliances.Test Signal Parameters and Interpretation
- Voltage rise and fall times during testing are clarified, emphasizing that these apply primarily to generator calibration, not directly to equipment under test (EUT) measurement.
- Annex F provides detailed guidance on correctly interpreting rise-time and fall-time requirements during immunity testing.
Three-Phase Systems Considerations
Includes notes on the variability of phase angle sign conventions for three-phase systems, which affects how test vectors are applied.Amendment Highlights
- Addition of clarification notes relating to three-phase system conventions.
- Inclusion of formula UL1-N = √(1+3P² )/2 for use in test vector calculations.
- Introduction of Annex F enhancing clarity on rise-time and fall-time test interpretations.
Applications
This standard is indispensable for industries and organizations that:
- Design, manufacture, and certify electrical equipment requiring compliance with EMC immunity levels, especially devices with high current inputs (over 16 A per phase).
- Conduct testing and validation of equipment to ensure continued operation during voltage dips, short supply interruptions, and voltage fluctuations, which are critical factors in power quality.
- Implement quality assurance processes for electrical products used in industrial environments, data centers, healthcare facilities, and commercial buildings where power disturbances are prevalent.
- Align product development with European and international EMC regulatory frameworks to facilitate market access and improve operational safety and reliability.
