IEC 60050-447:2010 defines terms specifically relevant to measuring relays. This first edition of IEC 60050-447, along with IEC 60050-444:2002 and IEC 60050-445:2002 cancels and replaces IEC 60050-446, published in 1983. It has the status of a horizontal standard in accordance with IEC Guide 108.

Abstract

Overview

Key Topics

IEC 60050-447:2010 covers a wide range of terminology associated with measuring relays, organized into systematic sections for ease of reference:

Relay Types: Definitions of various relay types, including electrical, measuring, electromechanical, electromagnetic, static, analog, digital, and numerical relays.
Relay Operation and Conditions: Terms relating to the states and operating principals of relays under different input conditions.
Energization: Vocabulary pertaining to relay energizing circuits and quantities.
Output Circuits: Descriptions of output circuits and mechanisms through which relays trigger changes in the system.
Time Characteristics: Definitions related to time delays, including specified-time, dependent-time, and independent-time relays.
Influence Quantities: Terms describing external factors or conditions that can affect relay performance.
Relay Characteristics: Key metrics, attributes, and performance descriptors for measuring relays.
Accuracy: Terminology specific to the precision of relay operations and measurements.

Each term is clearly defined and, where applicable, provided in multiple languages to support global standardization.

Applications

IEC 60050-447:2010 brings significant practical value in several areas of electrical engineering and standards development:

Standards Development: Used by technical committees to ensure precise and uniform language in international, national, and regional standards regarding measuring relays.
Product Documentation: Manufacturers and engineers apply the standardized vocabulary in technical datasheets, manuals, and compliance documents.
System Design and Integration: Power system designers and protection engineers reference these terms to specify and integrate measuring relays effectively in protection schemes.
Education and Training: Educational institutions use this vocabulary when teaching about electrical protection, measurement devices, and system automation.
Global Communication: Multinational projects benefit from the multilingual terminology, reducing ambiguity and enhancing cross-border collaboration and procurement.

By harmonizing the language around measuring relays, this standard promotes clarity, reduces misinterpretation, and supports reliable communication throughout the industry.

Related Standards

IEC 60050-447 forms part of a series alongside related terminology standards:

IEC 60050-444:2002 – Terms for elementary relays (non-specified time, all-or-nothing relays).
IEC 60050-445:2002 – Terms and definitions for specified-time relays.
IEC 60050-446 (superseded) – Previously covered relay terminology and now replaced by parts 444, 445, and 447 for improved clarity and division by relay type.
IEC Guide 108 – Provides guidelines for applying horizontal standards and ensuring coherence across IEC publications.

Together, these standards contribute to the unification and modernization of relay terminology for all professionals in the electrical and electronic sectors.

Keywords: IEC 60050-447, measuring relays, electrotechnical vocabulary, relay terminology, protection relays, IEC standards, electrical relays, power system protection, static relay, digital relay, accuracy, relay characteristics, international standards.
