EN 61000-4-30:2015/A1:2021 Overview
EN 61000-4-30:2015/A1:2021 is an important amendment to the European Standard for electromagnetic compatibility (EMC), specifically focusing on testing and measurement techniques for power quality measurement methods. Developed by CLC under the scope of electromagnetic compatibility, this amendment refines the procedures and requirements for accurate, reliable, and consistent measurement of power quality parameters.
This standard is harmonized with the corresponding IEC publication IEC 61000-4-30:2015/A1:2021 and is applicable throughout the CENELEC member countries. It serves as a vital reference for engineers, technicians, and organizations ensuring compliance with EMC directives and power quality regulations.
Key Topics Covered
Power Quality Measurement Techniques
The document provides enhanced guidelines on voltage quality measurement, focusing on parameters such as rms voltage, voltage events, and harmonic distortion under electromagnetic compatibility conditions.Measurement Uncertainty and Range
Amendments define stricter criteria for measurement uncertainty, especially for Class S instruments, requiring less than ±0.3% uncertainty for voltage (u) measurement. This ensures high accuracy in power quality assessments.RVC (Repeated Voltage Change) Event Detection
Updated logic for detecting RVC events includes:- Determining steady-state voltage over the previous 100/120 half-cycles.
- Criteria for the start and end of RVC events based on voltage steady-state changes.
- Application and removal of hysteresis during RVC events to improve detection reliability.
Crest Factor Specifications
Modifications clarify the requirements for the crest factor of current measurements, specifying changes in full-scale percentage measurement and accuracy levels to accommodate various classes of instruments.Standardization and Compliance Dates
The amendment was approved in April 2021, with mandatory implementation deadlines by January 2022 for national standard adoption and withdrawal of conflicting standards by April 2024.
Practical Applications
Power Quality Monitoring
EN 61000-4-30:2015/A1:2021 ensures consistent measurement quality for utilities and industries monitoring supply voltage characteristics, harmonics, and transient events.EMC Testing Laboratories
Testing facilities use these standardized methods to validate equipment compliance with EMC requirements, ensuring robust product development and certification.Grid Operators and Energy Providers
Enables grid operators to accurately assess and mitigate power disturbances, improving the reliability and efficiency of electricity delivery systems.Equipment Manufacturers
Manufacturers apply the standard to verify power quality measurement capabilities of their devices, from meters to analyzers, ensuring market acceptance and regulatory compliance.
