EN IEC 62053-23:2021/A11:2021

Overview

EN IEC 62053-23:2021/A11:2021 is a key European standard developed by CLC (CENELEC) that outlines the particular requirements for static meters measuring reactive energy of accuracy classes 2 and 3. This standard is specifically focused on static var-hour meters used in alternating current (AC) electrical installations operating at 50 Hz or 60 Hz. The document applies to type tests of these meters and ensures conformity with essential performance and safety requirements, particularly in the context of electromagnetic compatibility (EMC) under European legislation.

Key Topics

• Scope: The standard covers only those static meters intended for the measurement of AC reactive energy (expressed in var-hours), specifically addressing accuracy classes 2 and 3.
• Type Testing: It stipulates the procedures and requirements for type testing, ensuring meters meet defined criteria before being deployed.
• Electromagnetic Compatibility (EMC): The amendment aligns the requirements with the Directive 2014/30/EU for EMC, ensuring proper operation in environments with electromagnetic disturbances.
• Network Compatibility: Addresses meters used in both 50 Hz and 60 Hz power networks, supporting both industrial and utility grid applications.

Applications

Static meters conforming to EN IEC 62053-23:2021/A11:2021 are critical for:

• Utility Companies: Accurately measuring reactive energy consumption across large-scale electricity distribution networks, aiding in power quality management and grid stability.
• Industrial Facilities: Supplying reliable data on reactive energy, supporting operations management and optimizing electricity usage, particularly where power factor correction is essential.
• Compliance Assessment: Fulfilling requirements for conformity under the EMC Directive for equipment placed on the European market.
• Smart Metering Solutions: Forming the backbone of modern smart grids and digital metering infrastructures by providing precise and reliable measurement of reactive energy.
