Alkalmazási terület

This part of IEC 62052 applies only to newly manufactured multi-energy and/or multi-rate static meters and it applies to their type tests only. NOTE 1 For other general requirements, such as electrical, mechanical, safety, marking, dependability, etc., see the relevant parts of IEC 62052 or IEC 62059. For accuracy requirements and other requirements specific to class indices, see the relevant parts of IEC 62053. This document applies to electricity metering equipment designed to: - measure and control electrical energy on networks with voltage up to 1 000 V AC, or 1 500 V DC; 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. NOTE 3 For meters designed for operation with LPITs, only the metering unit is considered a low voltage device. If the LPITs are rated for voltages exceeding 1 000 V AC, or 1 500 V DC, the combination of the metering unit and LPITs is not a low voltage device. - have all functional elements, including add-on modules, enclosed in, or forming a single meter case with exception of indicating displays; - operate with integrated displays; - operate with 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. Meters designed for operation with Low Power Instrument Transformers (LPITs as defined in the IEC 61869 series) may be tested for compliance with this document and the relevant IEC 62053 series documents only if such meters and their LPITs are tested together as directly connected meters. NOTE 4 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 5 Product requirements for power monitoring devices and measurement functions such as voltage magnitude, current magnitude, power, frequency, etc., are covered in IEC 61557-12:2018. However, devices compliant with IEC 61557-12:2018 are not intended to be used as billing meters, unless they are also compliant with IEC 62052-11 and relevant IEC 62053-xx accuracy class standards. NOTE 6 Product requirements for power quality monitoring instruments are covered in IEC 62586-1:2017. Requirements for power quality measurement techniques (functions) are covered in IEC 61000-4-30:2015. Requirements for testing of the power quality measurement functions are covered in IEC 62586-2:2017. This document does not apply to: - meters for which the line-to-neutral voltage derived from nominal voltages exceeds 1 000 V AC, or 1 500 V DC; - meters intended for connection with low power instrument transformers (LPITs as defined in the IEC 61869 series of standards) when tested without such transformers; - metering systems comprising multiple devices (except for LPITs) physically remote from one another; - portable meters; NOTE 7 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; NOTE 8 Nominal values, accuracy classes, requirements and test methods for reference standard meters are specified in IEC 62057-1 (First edition under preparation. Stage at the time of publication: IEC FDIS 62057-1:2022). - data interfaces to the register of the meter; - matching sockets or racks used for installation of electricity metering equipment. This document does not cover measures for the detection and prevention of fraudulent attempts to compromise a meter’s performance (tampering).
