Anotace:

This part of IEC 62053 applies only to newly manufactured static watt-hour meters of accuracy classes 0,5, 1 and 2 for the measurement of alternating current electrical active energy in 50 Hz or 60 Hz networks and it applies to their type tests only.

Note 1: 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 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 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.
