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