Overview
EN IEC 62053-24:2021/A11:2021 is a CLC/CENELEC amendment to the European standard for static var‑hour meters (reactive energy meters). It applies to type tests only for static meters that measure the fundamental component of reactive energy in 50 Hz or 60 Hz networks, covering accuracy classes 0,5S, 1S, 1, 2 and 3. Amendment A11 updates the 2021 Part 24 requirements and supports conformity with EU electromagnetic compatibility rules.
Key topics and requirements
- Scope and applicability: Type testing of static meters for fundamental component reactive energy in alternating‑current networks (50/60 Hz).
- Accuracy classes: Requirements and classification for meters in 0,5S, 1S, 1, 2 and 3 accuracy classes.
- Electromagnetic compatibility (EMC): Normative and informative provisions mapping to Directive 2014/30/EU (Annex ZZ) - includes immunity and emissions considerations relevant to meter performance.
- Immunity tests referenced: Examples included in the amendment and Annex ZZ (as part of the EMC relationship) - radiated RF field immunity, electrical fast transient/burst (EFT), conducted disturbances induced by RF fields, conducted differential mode disturbances (2 kHz–150 kHz), damped oscillatory wave, external and power‑frequency magnetic field immunity.
- Distortion and harmonic testing: Tests related to harmonics, interharmonics and half‑wave rectified waveforms that affect reactive energy measurement.
- Type testing only: This document governs the type test protocols and does not replace routine on‑site or in‑service testing requirements.
Applications and who uses it
- Utility companies and distribution system operators - for procurement, type approval and ensuring accurate reactive energy measurement for billing and network management.
- Meter manufacturers and designers - to design, test and certify static reactive energy meters to specified accuracy classes and EMC performance.
- Notified bodies, conformity assessment and testing laboratories - for conducting type tests and issuing compliance reports.
- Regulators and standards committees - for harmonisation of national standards and enforcement against Directive 2014/30/EU requirements.
Related standards and context
- Part of the broader IEC/EN 62053 family of electricity metering standards (electricity metering equipment - particular requirements).
- Linked to Directive 2014/30/EU (EMC) via Annex ZZ - compliance with cited clauses provides presumption of conformity for EMC within the standard’s scope.
- Amendment status: EN IEC 62053-24:2021/A11:2021 (approved by CENELEC 2021-05-19) - national adoption and withdrawal timelines are defined by CENELEC.
