IEC 61869 is the international standards series that covers requirements, testing, performance, and application guidance for modern instrument transformers (voltage and current transformers) used for measurement and protection in power systems. It replaced and consolidated much of the older IEC 60044 series to reflect newer accuracy classes, safety, and digital interface considerations.
If a conflict arises between Part 1 and a subsequent "product part" (like Part 2 or 3), the specific product part takes precedence.
The standard applies to newly manufactured instrument transformers used for:
Pro Tip: If you work for a utility or engineering firm, ask your internal librarian or standards committee for access. Many large organizations have an IEC site license covering all standards.
Environmental Conditions: Specifies requirements for normal and special service conditions, such as temperature, altitude, vibration, and pollution levels.
