Alkalmazási terület

1.1 General This part of IEC 62052 specifies general safety requirements and associated tests, with their appropriate conditions for type testing of directly connected, transformer-operated or transducer-operated AC and DC electricity meters and load control equipment. NOTE 1 For other general requirements, such as EMC, dependability, etc., see the relevant IEC 62052 or IEC 62059 standards. For accuracy requirements and other requirements specific to class indices, see the relevant IEC 62053 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 AC or 1 500 V DC; NOTE 2 The voltage mentioned above is the line-to-neutral voltage AC RMS or DC derived from nominal voltages. See Table 7. - have all functional elements, including add-on communication modules, enclosed in, or forming a single meter case with exception of indicating displays; - operate with integrated displays (electromechanical or static meters); - operate with detached indicating displays or without an indicating display (static meters only); - wall-mounted or to be installed in specified matching sockets or racks; - 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, and 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 (PMDs) 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 IEC 62053-xx particular requirements (accuracy class) standard. NOTE 5 Product requirements for Power Quality Instruments (PQIs) are covered in IEC 62586-1. Requirements for power quality measurement techniques (functions) are covered in IEC 61000-4-30. Requirements for testing of the power quality measurement functions are covered in IEC 62586-2. This document also applies to transducer-operated meters or meters designed for operation with Low Power Instrument Transformers (LPIT) or sensors (as defined in the IEC 61869 series). NOTE 6 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. When equipment in scope of this document is designed to be installed in a specified matching socket, then the requirements apply to, and the tests are performed on, equipment installed in its specified matching socket. However, requirements for sockets and inserting / removing the meters from the socket are outside the scope of this document. This document is also applicable to auxiliary input and output circuits, operation indicators, and test outputs of equipment for electrical energy measurement. NOTE 7 Some examples include impulse inputs and outputs, control inputs and outputs, energy test outputs, and circuits for meter data exchange. Equipment used in conjunction with equipment for electrical energy measurement and control may need to comply with additional safety requirements. See also Clause 13. NOTE 8 Examples are telecommunication modems and customer information units. This document does not apply to: - meters rated to operate with voltage exceeding 1 000 V AC, or 1 500 V DC; - metering systems comprising multiple devices physically remote from one another; - portable meters; NOTE 9 Portable meters are meters that are not permanently connected. - meters used in rolling stock, vehicles, ships and airplanes; - laboratory and mobile meter test equipment; - reference standard meters; NOTE 10 Nominal values, accuracy classes, requirements and test methods for reference standard meters are specified in IEC 62057-1: 2023. - conventional or low power instrument transformers; NOTE 11 Safety of conventional power transformers and low power instrument transformers is covered in the IEC 61869 series of standards. - equipment with solid-state or other non-electromechanical supply and load control switches. NOTE 12 For components and sub-assemblies, see Clause 13. túl hosszú Scope
