IEC 60255-1:2022 Measuring relays and protection equipment – Part 1: Common requirements

IEC 60255-1:2022 establishes the general technical requirements for measuring relays and protection equipment used in power systems. It defines basic terms, rated values, construction, safety, insulation, temperature rise, marking, and testing conditions, providing a unified framework for product design, manufacturing, and evaluation.

This standard specifies the common performance and safety criteria to ensure the reliability and consistency of measuring relays and protection equipment. It covers essential requirements including electrical clearances, functional safety, test methods, and documentation, serving as a fundamental reference for product certification, inspection, and compliance worldwide.
