Overview

SIST EN IEC 62053-23:2021/A11:2021 is a European standard issued by CLC that specifies particular requirements for static meters used in measuring reactive energy in electric power systems. Targeting static var-hour meters of accuracy classes 2 and 3, this standard governs the type testing of these meters within 50 Hz or 60 Hz alternating current networks. It serves as an amendment to the base standard EN IEC 62053-23:2021, ensuring updated compliance with current metrological and electromagnetic compatibility demands.

As part of the IEC 62053 series, this standard supports reliable and precise measurement of reactive power, which is critical for efficient electricity supply systems and accurate billing processes. It applies primarily to static meters-electronic devices that record reactive energy consumption without moving parts-emphasizing durability and consistency in performance.

Key Topics

• Static Reactive Energy Meters: Definitions and specifications for static (solid-state) meters measuring reactive energy expressed in var-hours.
• Accuracy Classes 2 and 3: Performance requirements detailing permitted measurement errors aligned with these accuracy classes.
• Type Testing Requirements: Procedures and conditions under which meters must be tested to verify compliance with accuracy and electromagnetic compatibility.
• Frequency Application: Applicability to 50 Hz and 60 Hz alternating current networks, covering major utility frequency standards globally.
• Electromagnetic Compatibility (EMC): Compliance with Directive 2014/30/EU, including tests for immunity to electromagnetic disturbances such as radiated fields, conducted disturbances, harmonics, and magnetic interference.
• Harmonization and Adoption: Guidance on implementing the amendment as a national standard across CENELEC member countries, supporting unified regulatory compliance throughout Europe.

Applications

SIST EN IEC 62053-23:2021/A11:2021 is essential for manufacturers, testing laboratories, and utility companies involved with:

• Electricity Meter Manufacturing: Ensuring static reactive energy meters meet stringent accuracy and EMC requirements before market deployment.
• Utility Metering and Billing: Accurate metering of reactive energy to facilitate proper billing and energy management in low and medium voltage networks.
• Energy Auditing and Monitoring: Reliable measurements for assessing reactive power flow in electrical installations to optimize power factor correction strategies.
• Type Approval and Certification: Providing a benchmark for conformity assessment bodies issuing certifications required for market access.
• Electromagnetic Compatibility Compliance: Reducing interference and improving safety by adhering to harmonized EMC testing protocols specified in the standard.

Related Standards

• IEC 62053 Series: Covers a range of electricity metering equipment requirements, including active energy meters.
• EN IEC 62053-23:2021: The base standard for static meters for reactive energy, to which this document is an amendment.
• Directive 2014/30/EU: European EMC Directive supported by this standard to ensure device interoperability and safety.
• ISO/IEC Standards on Electrical Metering: Complementary standards providing additional specifications and testing procedures for metering technologies.
• Other CLC Electrotechnical Standards: Standards addressing electrical measurement, power quality, and smart metering infrastructure.
