IEC 62052-11: Static meters for active energy

This standard focuses on static meters designed to measure active electrical energy in AC networks. It covers a wide range of meters, including:

Single-phase meters: Used for measuring energy in single-phase circuits.
Three-phase meters: Used for measuring energy in three-phase circuits.
Multi-function meters: Capable of measuring various electrical parameters in addition to energy, such as voltage, current, power factor, and harmonics.

Key aspects covered in IEC 62052-11:

Definitions: Provides clear definitions of terms used in energy metering, such as active energy, reactive energy, power factor, and harmonics.
Functional requirements: Specifies the functional requirements for static meters, including measurement accuracy, response time, and overload protection.
Test methods: Outlines the test procedures to be used for verifying the performance of static meters.
Environmental conditions: Defines the environmental conditions under which static meters should operate, such as temperature, humidity, and electromagnetic interference.
Marking: Specifies the marking requirements for static meters, including the manufacturer's name, model number, and rated values.

IEC 62053-21: AC static meters for active energy

IEC 62053-21 is a more specific standard that focuses solely on AC static meters for active energy. It provides additional requirements and test methods for these types of meters.

Key differences between IEC 62052-11 and IEC 62053-21:

Scope: IEC 62053-21 has a narrower scope, focusing exclusively on AC static energy meters.
Additional requirements: IEC 62053-21 may include additional requirements or more stringent test methods compared to IEC 62052-11.
