IEC 62053-23-2020 pdf free download – Electricity metering equipment – Particular requirements – Part 23: Static meters for reactive energy (classes 2 and 3).
For practical reasons,this document is based on a conventional definition of reactive energyfor sinusoidal currents and voltages containing the fundamental frequency only.
NOTE1 For other general requirements,such as safety，dependablity,etc.， see the relevant EC 62052 orEC 62059 standards.
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 nominalvoltages. See EC 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，prowde additional functions other than those for measurement of electricalenergy.
Meters designed for operation with low power instrument transformers (LPlTs as defined in theIEC 61869 series) may be considered as compliant with this document only if such meters andtheir LPIlTs are tested together and meet the requirements for directly connected meters.
NOTE 3 Modern electricity meters typically contain additional functions such as measurement of voltage magn itude,current magnitude，pow er，frequency，power factor, etc;measurement of power quality parameters;load controlfunctions; delvery， tirme，test, accounting,recording functions; data communication interfaces and associated datasecurity functions. The relevant standards for these functions may apply in addition to the requirements of thisdocument. How ever，the requirements for such functions are outside the scope of this document.
NOTE4 Poduct requirements for pow er metering and monitoring devices (PMDs) and measurement functions suchas voltage magnitude,current magnitude,pow er，frequency， elc.， are covered in EC 61557-12. How ever，devicescompliant with EC 61557-12 are not intended to be used as billing meters unless they are also compliant withlEC62052-11:2020 and one or more relevant EC 62053-xx accuracy class standards.
NOTE 5 Poduct requirements for power qualify instruments (PQs) are covered in lEC 62586-1.Requirements forpow er quality measurement techniques (functions) are covered in lEC 61000-4-30.Requirements for testing of thepow er quality measurement functions are covered in lEC 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 (LPITs as definedin the IEC 61869 series) when tested without such transformers;
metering systems comprising multiple devices (except LPITs) physically remote from oneanother;
portable meters;
NOTE 6 Portable meters are meters that are not permanentlyconnected.. 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 attemptsto compromise a meter’s performance (tampering).
NOTE 7 Nevertheless，specific tampering detection and prevention requirements, and test methods，as relevant fora particular market are subject to the agreement betw een the manufacturer and the purchaser.
NOTE 8 Specifying requirements and test methods for fraud detection and prevention would be counterproductive,as such specifications would provide guidance for potential fraudsters.
NOTE 9 There are many types of meter tampering reported from various markets; therefore,designing meters todetect and prevent all types of tampering could lead to unjustfied increase in costs of meter design,verification andvalidation.
NOTE10 Billing systems,such as, smart metering systems,are capable of detecting irregular consumption patternsand irregular netw ork losses which enable discovery of suspected ‘meter tampering.
NOTE 11 For transformer operated meters paired with current transfomers (CTs) according to lEC 61869-2:- the standard CT measuring range is specified from 0,05 In to Imax for accuracy classes 0,1,0.2,0.5 and 1 andthese CTs are used for meters of class 2 and 3 according to this document;
the special CT measuring range is specified from 0,01 In to Imaxw for accuracy classes 0,2S and 0,5 S and theseCTs are used for meters of class o,5 s and 1S according to EC 62053-24;
combinations of standard CTs and meters of class 0,5 S and 1 s are subiject to an agreement betweenmanufacturers and purchasers.
NOTE 12 This document does not specify emission requirements，these are specified in EC 62052-11:2020，9.3.14.
