Anotace textu normy ČSN EN IEC 62053-24-ed.2 (356132):

This part of IEC 62053 applies only to static var-hour meters of accuracy classes 2 and 3 for the measurement of alternating current electrical reactive energy in 50 Hz or 60 Hz networks and it applies to their type tests only. For practical reasons, this document is based on a conventional definition of reactive energy for sinusoidal currents and voltages containing the fundamental frequency only. NOTE 1 - For other general requirements, such as safety, dependability, etc., see the relevant IEC 62052 or IEC 62059 standards. This document applies to electricity metering equipment designed to: 1. measure and control electrical energy on electrical networks (mains) with voltage up to 1 000 V; NOTE 2 - For AC electricity meters, the voltage mentioned above is the line-to-neutral voltage derived from nominal voltages. See IEC 62052-31:2015, Table 7. 2. have all functional elements, including add-on modules, enclosed in, or forming a single meter case with exception of indicating displays; 3. operate with integrated or detached indicating displays, or without an indicating display; 4. be installed in a specified matching socket or rack; 5. optionally, provide additional functions other than those for measurement of electrical energy. Meters designed for operation with low power instrument transformers (LPITs as defined in the IEC 61869 series) may be considered as compliant 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, 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 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 IEC 62052-11:2020 and one or more relevant IEC 62053-xx accuracy class standards. 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
