Full title and description

IEC TR 62059-11:2002 — Electricity metering equipment — Dependability — Part 11: General concepts. This Technical Report presents general concepts and guidance on the dependability (reliability, availability, maintainability and related attributes) of static electrical energy metering equipment and associated load-control functions; it is intended to inform designers, manufacturers, test houses and utilities about dependability aspects relevant to static meters and load-control devices.

Abstract

The report covers general aspects of dependability for static metering equipment used for electrical energy measurement and for load control, including high‑level concepts, terminology and considerations that affect meter performance over its lifecycle. It is intended as guidance rather than as a normative specification and is of particular relevance where metering is used in advanced network and Smart Grid applications.

Scope

This Technical Report provides general concepts and guidance relevant to the dependability of static (solid‑state) electricity metering equipment used for energy measurement and for load control. It addresses high‑level dependability topics (definitions, general design and verification considerations, environmental and operational influences, and how dependability relates to metering accuracy and functionality) rather than prescriptive test procedures. The guidance is applicable to manufacturers, test laboratories and utilities assessing or designing static meters and related load‑control devices.

Key topics and requirements

• Fundamental dependability concepts and terminology for metering equipment (reliability, availability, maintainability, safety‑related dependability aspects).
• Identification of typical failure modes and degradations affecting static meters and load‑control units.
• Reliability and availability objectives and how they relate to metering performance and regulatory requirements.
• Design and environmental considerations that influence long‑term dependability (thermal, humidity, EMC, mechanical stress, power‑quality impacts).
• Guidance on maintainability, diagnostics and self‑monitoring features to support dependable operation.
• High‑level recommendations for verification and assessment approaches (to be used in conjunction with normative test standards in the IEC 62059 series and related documents).

Typical use and users

Primary users are electricity meter manufacturers, design engineers, product managers, test laboratories, utilities and distribution system operators, regulators and standards developers. The report is used as background guidance during product development, reliability planning, conformity assessment and when specifying dependability aspects in procurement or regulatory documents. Researchers and consultants working on Smart Grid metering strategies also use it for high‑level dependability context.

FAQ

Q: What is this standard?

A: IEC TR 62059‑11:2002 is a Technical Report from IEC Technical Committee TC 13 that gives general concepts and guidance on the dependability (reliability, availability, maintainability and related aspects) of static electrical energy metering equipment and load‑control devices.

Q: What does it cover?

A: It covers high‑level dependability concepts, typical failure modes, environmental and operational considerations, maintainability and diagnostic recommendations, and how dependability considerations interact with metering performance. It is guidance rather than a prescriptive test specification.

Q: Who typically uses it?

A: Meter manufacturers, designers, test laboratories, utilities and regulators use the report for background guidance on dependability when designing, testing or procuring static metering and load‑control equipment. Researchers and consultants working on Smart Grid metering strategies may also consult it.

Q: Is it current or superseded?

A: The document was published on 29 January 2002 (Edition 1.0). According to IEC metadata the publication has a declared stability horizon (stability date) noted by IEC; users should check the IEC webstore or their national standards body for any amendments, national adoptions or later parts of the IEC 62059 series. As of the IEC publication record, the TR remains the 2002 edition; confirm with your national body for the latest status before relying on it for regulatory compliance.

Q: Is it part of a series?

A: Yes — it is Part 11 of the IEC 62059 set of documents addressing dependability of electricity metering equipment; other parts in the series provide more specific guidance and test methods. Users often consult this TR together with other IEC 62059 parts and related IEC test and vocabulary standards.
