The IEC 61869-1:2023 Edition 2.0 standard updates the Product Family requirements for instrument transformers by integrating low-power (LPIT) requirements and expanding application scope to systems over 1 kV AC/1.5 kV DC. Key changes include new wideband accuracy classes for harmonics, updated test classifications, and the continued replacement of the IEC 60044 series. The document is available at the IEC Webstore . IEC 61869-1:2023
, represents a significant technical revision that merges previous standards and introduces modernized requirements for the digital era. You can find the official document through the IEC Webstore or authorized distributors like iTeh Standards 1. Scope and Core Purpose

The IEC 61869 series, managed by the International Electrotechnical Commission (IEC) Technical Committee 38, is a unified product family standard. It replaced the aging IEC 60044 framework to establish a standardized approach to instrument transformers. While specific types of hardware—such as current transformers or voltage transformers—are governed by their respective sub-parts (e.g., IEC 61869-2), . Every specialized transformer standard must be read in tandem with the general rules established in Part 1. The standard applies directly to hardware feeding: Electrical measuring instruments Electrical protective relays and control systems

For manufacturers and utility procurement teams, compliance is non-negotiable. Engineering procurement, construction (EPC) contracts, and international utility tenders strictly mandate compliance with the latest revisions of IEC 61869-1. Accessing the precise document is essential for running pre-commissioning tests, verifying type-test certificates, and avoiding costly project delays. Summary of the IEC 61869 Standard Structure
