Instrument transformers play a crucial role in power systems, enabling accurate measurement and monitoring of current and voltage levels. IEC 61869-1 is a widely adopted standard for instrument transformers, outlining the requirements for their design, testing, and operation. This paper provides a comprehensive review of IEC 61869-1, covering its scope, key definitions, and technical requirements. We also discuss the benefits and challenges of implementing this standard in power systems.
The International Electrotechnical Commission (IEC) developed the IEC 61869 series to unify and replace older standard frameworks (specifically the legacy IEC 60044 series). iec 618691 pdf hot
IEC 61869-1:2023 is the latest "product family" standard governing the general requirements for instrument transformers. It serves as a foundational document that must be used in conjunction with specific product standards (like Part 2 for current transformers or Part 3 for voltage transformers).
