IEC 61869-1 is the international standard titled “Instrument transformers – Part 1: General requirements.” Published by the International Electrotechnical Commission (IEC), this document serves as the umbrella specification for all instrument transformers.
It replaced the older IEC 60044 series (which covered traditional CTs and VTs) and the IEC 60044-7 and -8 (for electronic transformers). The 61869 series harmonizes requirements for both conventional and emerging technologies into a single, coherent framework.
Key Update Note: The most current version widely referenced today is IEC 61869-1:2007 + AMD1:2021 (Edition 2.1). Any reliable IEC 61869-1 PDF should reflect these amendments. To download a legitimate copy:

This is a critical section for safety. It details power-frequency withstand voltage, lightning impulse tests, and partial discharge limits. The standard ensures that transformers can survive overvoltages without failing catastrophically.
