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 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 designed to:
• measure and control electrical energy on networks with voltage up to 1,000 V a.c, or 1,500 V d.c;
Note 2: 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 single meter case with exception of indicating displays;
• operate with integrated or detached indicating displays, or without an indicating display.
• be installed in a specified matching sockets or racks;
• 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, 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 standard. However, the requirements for such functions are outside the scope of this standard.
Note 4: Product requirements for power monitoring devices 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 and a relevant IEC 62053-xx accuracy class standards.
Note 5: Product requirements for power quality monitoring instruments 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.
