The IEC 62052-11 standard specifies the general requirements, testing methodologies, and test conditions for electricity metering equipment used in alternating current (AC) systems. It covers essential aspects such as the functional and performance characteristics, mechanical construction, and safety requirements to ensure the accuracy, reliability, and durability of metering devices. The standard is applicable to all types of electricity meters, including those used for active energy (kWh) and reactive energy (kVARh), and includes provisions for compliance with environmental and electromagnetic compatibility (EMC) requirements.
Additionally, IEC 62052-11 outlines detailed procedures for testing metering equipment under various operating conditions to validate performance against specified criteria. These tests include climatic, electrical, and mechanical tests to simulate real-world scenarios. The standard aims to harmonize global metering practices, ensuring consistent quality and interoperability across devices from different manufacturers while adhering to regulatory and market needs.
