This part of IEC 62053 applies only to newly manufactured static var-hour meters of accuracy classes 0,5S, 1S, 1, 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.

This standard uses a conventional definition of reactive energy where the reactive power and energy is calculated from the fundamental frequency components of the currents and voltages only (see clause 3, Terms and definitions).

Note 1 This differs from IEC 62053-23, where reactive power and energy is only defined for sinusoidal signals. In this standard reactive power and energy is defined for all periodic signals. Reactive power and energy is defined in this way to achieve proper reproducibility of measurements with meters of different designs. With this definition, reactive power and energy reflects the generally unnecessary current possible to compensate with capacitors rather than the total unnecessary current.

Note 2: For other general requirements, such as safety, dependability etc., see the relevant IEC 62052 or IEC 62059 standards

This International Standard applies to newly manufactured electricity metering equipment designed 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 3:  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 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.

Meters designed for operation with low power instrument transformers (LPITs as defined in the IEC 61869 series of standards) may be considered as compliant with this international standard only if such meters and their LPITs are tested together, and meet the requirements for directly connected meters.

This part of IEC 62053 applies only to newly manufactured 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 standard is based on a conventional definition of reactive energy for sinusoidal currents and voltages containing the fundamental frequency only.

This International Standard describes how the DLMS/COSEM Application layer and the COSEM object model as specified in IEC 62056-5-3:2017, IEC 62056-6-1 and IEC 62056-6-2:2017 can be used over the lower layers specified in IEC 14908 series, forming a DLMS/COSEM ISO/IEC 14908 communication profile.

This document is part of the IEC 62056 series. Its structure follows IEC 62056-1-0 and IEC TS 62056-1-1.

Annex A (informative) provides examples of representative instances of data exchange.

NOTE   This Annex is included and referenced for consistency with other parts of the IEC 62056 suite, but it is empty.

Annex B (normative) defines COSEM interface classes and related OBIS codes for setting up and managing the DLMS/COSEM communication profile for IEC 14908 networks. These interface classes and OBIS codes will be moved later to IEC 62056-6-2 and IEC 62056-6-1.

Annex C (informative) provides an implementation guide and specifies a migration path from Utility Tables based applications to DLMS/COSEM based applications

Annex D (normative) specifies the OSGP-AES-128-PSK security suite for optional use on the adaptation layer level.

Annex E (normative) specifies the repeating mechanism over  the ISO 14908-3 Power Line Channel network.

Annex F (informative) specifies ISO/IEC 14908-3 Registration and monitoring of LNAPs.
