IEC 62053-23:2020 applies only to static var-hour meters of accuracy classes 2 and 3 for the measurement of alternating current electrical reactive energy in 50 Hz or 60 Hz networks and it applies to their type tests only.
\nFor practical reasons, this document is based on a conventional definition of reactive energy for sinusoidal currents and voltages containing the fundamental frequency only.
\nThis document applies to electricity metering equipment designed to:
\n\u2022 measure and control electrical energy on electrical networks (mains) with voltage up to 1 000 V AC;
\n\u2022 have all functional elements, including add-on modules, enclosed in, or forming a single meter case with exception of indicating displays;
\n\u2022 operate with integrated or detached indicating displays, or without an indicating display;
\n\u2022 be installed in a specified matching socket or rack;
\n\u2022 optionally, provide additional functions other than those for measurement of electrical energy.
\nMeters designed for operation with low power instrument transformers (LPITs as defined in the IEC 61869 series) may be considered as compliant with this document only if such meters and their LPITs are tested together and meet the requirements for directly connected meters.
\nThis document does not apply to:
\n\u2022 meters for which the voltage line-to-neutral derived from nominal voltages exceeds 1 000 V AC;
\n\u2022 meters intended for connection with low power instrument transformers (LPITs as defined in the IEC 61869 series) when tested without such transformers;
\n\u2022 metering systems comprising multiple devices (except LPITs) physically remote from one another;
\n\u2022 portable meters;
\n\u2022 meters used in rolling stock, vehicles, ships and airplanes;
\n\u2022 laboratory and meter test equipment;
\n\u2022 reference standard meters;
\n\u2022 data interfaces to the register of the meter;
\n\u2022 matching sockets or racks used for installation of electricity metering equipment;
\n\u2022 any additional functions provided in electrical energy meters.
\nThis document does not cover measures for the detection and prevention of fraudulent attempts to compromise a meter\u2019s performance (tampering).
\nThis second edition cancels and replaces the first edition published in 2003 and its amendment 1:2016. This edition constitutes a technical revision.
\nThis edition includes the following significant technical changes with respect to the previous edition:
\na) Removed all meter safety requirements; the meter safety requirements are covered in IEC 62052-31:2015.
\nb) Replaced Ib with In; Ib is no longer used when referencing directly connected meters.
\nc) Moved the descriptions of all general requirements and test methods from IEC 62053-21: 2003, IEC 62053-22: 2003, IEC 62053-23: 2003, IEC 62053-24: 2003 to IEC 62052-11:2020; IEC 62053-21:2020, IEC 62053-22:2020, IEC 62053-23:2020, IEC 62053-24:2020 contain only accuracy class specific requirements.
\nd) Added new requirements and tests concerning:
\n1) measurement uncertainty and repeatability (7.3, 7.8);
\n2) influence of fast load current variations (9.4.12);
\n3) immunity to conducted differential current disturbances in the 2 kHz to 150 kHz frequency range (9.3.8).
\ne) Meters designed for operation with low power instrument transformers (LPITs) may be tested for compliance with this document as directly connected meters.
\nThe reactive energy accuracy classes 2 and 3 defined in IEC 62053-23 have also been added to IEC 62053-24. The TC13 WG11 is of the opinion that the testing methodology described in IEC 62053-24 is a better approach to testing of modern reactive energy meters. Consequently, IEC 62053-23 will be withdrawn in the near future, and should not be used for new meter designs.<\/p>\n","protected":false},"excerpt":{"rendered":"
