Electricity metering equipment. Particular requirements. Part 41: Static meters for DC energy (classes 0,5 and 1) (IEC 62053-41:2021)

Alkalmazási terület

This part of IEC 62053 applies only to static watt-hour meters of accuracy classes 0,5 and 1 for the measurement of DC electrical energy in DC systems, and it applies to their type tests only. NOTE 1 For other general requirements, such as safety, dependability, etc., see the relevant parts of IEC 62052 or IEC 62059. This document applies to electricity metering equipment designed to: - measure and control electrical energy on electrical networks with two poles where one of the poles is connected to earth and with voltage up to 1 500 V DC; NOTE 2 There are DC networks with other configurations or with more than 2 poles (for example networks with earth and both a positive and a negative pole). - have all functional elements, including add-on modules, enclosed in, or forming a single meter case with the 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. The electricity metering equipment covered by this document may be used for measuring DC electrical energy in the following, or similar, application areas: - in EV (electrical vehicle) charging stations or in EV charging infrastructures, if the measurement is placed on the DC side; - in information technology (IT) server farms; - in DC supply points for communication equipment; - in low voltage DC networks for residential or commercial areas, if the measurement is placed on the DC side; - in solar PV (photovoltaic) systems where DC power generation is measured; - in DC supply points for public transport networks (e.g. trolleybus, etc.). 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 only if such meters and their LPITs 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 magnitude, current magnitude, power, 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. This document does not apply to: - meters for which the voltage between the two poles, where one of the poles is connected to earth, exceeds 1 500 V DC; - meters to be used in networks other than with two poles in which one of the poles is connected to earth; - 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 (except LPITs) remote from one another; - portable meters; NOTE 4 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; - 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 detection and prevention of fraudulent attempts to compromise a meter’s performance (tampering). NOTE 5 Nevertheless, specific tampering detection and prevention requirements, and test methods, as relevant for a particular market are subject to agreement between the manufacturer and the purchaser. NOTE 6 Specifying requirements and test methods for fraud detection and prevention would be counterproductive, as such specifications would provide guidance for potential fraudsters. NOTE 7 There are many methods of tampering with meters reported from various markets; designing meters to detect and prevent all kinds of tampering would lead to unjustified increase in costs of meter design, verification and validation. NOTE 8 Billing systems, such as, smart metering systems, are capable of detecting irregular consumption patterns and irregular network losses which enable discovery of suspected meter tampering. NOTE 9 This document does not specify emission requirements, these are specified in IEC 62052-11:2020, 9.3.14. NOTE 10 DC meters for rolling stock are covered by other IEC standards, e.g., from TC 9 for railway applications: IEC 62888-1:2018, IEC 62888-2:2018, IEC 62888-3:2018, IEC 62888-4:2018, IEC 62888-5:2018.
