BS EN IEC 62053-22:2021 pdf free.Electricity metering equipment – Particular requirements Part 22: Static meters for AC active energy (classes 0,1S, 0,2S and 0,5S).
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;
NOTE 2 For AC electricity meters, the voltage mentioned above is the line-to-neutral voltage derived from nominal
voltages See IEC 62052-31:2015, Table 7.
• 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.
NOTE 3 Modern electricity meters typically contain additional functions such as measurement of voltage magnitude, current magnitude, power, frequency, power factor, etc. measurement of power quality parameters; load control functions; delivery, time, test, accounting, recording functions; data communication interfaces and associated data security functions. The relevant standards for these functions may apply in addition to the requirements of this document. However, the requirements for such functions are outside the scope of this document.
NOTE 4 Product requirements for power metering and monitoring devices (PMD5) and measurement functions such as voltage magnitude, current magnitude, power, frequency. etc.. are covered in IEC 61557-12. However, devices compliant with IEC 61557-12 are not intended to be used as billing meters unless they are also compliant with the IEC 62052-11:2020 and one or more relevant lEG 62053-xx accuracy class standards.
NOTE 5 Product requirements for power quality instruments (P015) are covered in IEC 62586.1. Requirements for power quality measurement techniques (functions) are covered in IEC 6 1000-4-30. Requirements for testing of the power quality measurement functions are covered in IEC 62586-2,
This document does not apply to:
• meters for which the voltage line-to-neutral derived from nominal voltages exceeds 1 000 V;
• meters intended for connection with low power instrument transformers (LPIT5 as defined in the IEC 61869 series) when tested without such transformers;
• metering systems comprising multiple devices physically remote from one another.
• portable meters:
NOTE 6 Portable meters are meters that are not permanently connected.
• 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;
