DANSK DSF/PREN IEC 62052-11 PDF

This part of IEC 62052 specifies requirements and associated tests, with their appropriate conditions for type testing of a.c. and d.c. electricity meters. This part details functional, m e- chanical, marking and electrical requirements including immunity to external influences cover- ing electromagnetic and climatic environments. Note 1: For other general requirements, such as safety, 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 International Standard applies to newly manufactured electricity metering equipment de- signed to: • measure and control electrical energy on electrical networks (mains) with voltage up to 1,000 V a.c, or 1,500 V d.c.; Note 2: For a.c. electricity meters, the voltage mentioned above is the line-to-neutral voltage derived from nominal voltages. See IEC 62052-31:2015 Table 7. • have all functional elements, including add-on modules, enclosed in, or forming a sin- gle meter case with exception of indicating displays; • operate with integrated or detached indicating displays, or without an indicating dis- play; • be installed in a specified matching sockets or racks; • provide additional functions other than those for m easurement of electrical energy.
