IEC 62053-22:2020 applies only to transformer operated static watt-hour meters of accuracy classes 0,1 S, 0,2 S and 0,5 S for the measurement of alternating current electrical active energy in 50 Hz or 60 Hz networks and it applies to their type tests only.
This document applies to electricity metering equipment designed to:
？ measure and control electrical energy on electrical networks (mains) with voltage up to 1 000 V AC;
？ have all functional elements, including add-on modules, enclosed in, or forming a single meter case with exception of indicating displays;
？ operate with integrated or detached indicating displays, or without an indicating display;
？ be installed in a specified matching socket or rack;
？ optionally, provide additional functions other than those for measurement of electrical energy.
This document does not apply to:
？ meters for which the voltage line-to-neutral derived from nominal voltages exceeds 1 000 V AC;
？ meters intended for connection with low power instrument transformers (LPITs as defined in the IEC 61869 series) when tested without such transformers;
？ metering systems comprising multiple devices physically remote from one another.
？ portable meters;
？ meters used in rolling stock, vehicles, ships and airplanes;
？ laboratory and meter test equipment;
？ reference standard meters;
？ data interfaces to the register of the meter;
？ matching sockets or racks used for installation of electricity metering equipment;
？ any additional functions provided in electrical energy meters.
This document does not cover measures for the detection and prevention of fraudulent attempts to compromise a meter’s performance (tampering)
This second edition cancels and replaces the first edition published in 2003 and its amendment 1: 2016. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) Removed all meter safety requirements; the meter safety requirements are covered in IEC 62052-31: 2015.
b) 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.
c) Added new requirements and tests concerning:
1) active energy meters of accuracy class 0,1S;
2) measurement uncertainty and repeatability (7.3, 7.8);
3) influence of fast load current variations (9.4.12);
4) immunity to conducted differential current disturbances in the 2 kHz to 150 kHz frequency range (9.3.8)
