Deep Feature: The "Product Family" Restructuring
The most significant feature of IEC 61869-1 is its role as the foundational "Product Family" standard for all instrument transformers.
Consolidation of Requirements: It replaces and integrates the "general requirements" previously scattered across the older IEC 60044 series.
Modular Application: This standard does not stand alone; it provides the core principles—such as insulation levels, temperature rise limits, and electromagnetic compatibility—that must be paired with specific "Additional Requirements" documents (like Part 2 for current transformers or Part 3 for inductive voltage transformers).
Latest 2023 Revision: The newest edition (IEC 61869-1:2023) has further expanded this feature by merging with IEC 61869-6:2016, now covering high-voltage applications (> 1 kV AC or 1.5 kV DC) and incorporating digital secondary signals into the general framework.
