This standard specifies the for instrument transformers (Current Transformers and Voltage Transformers). It acts as a "parent" standard; product-specific standards (like Part 2 for CTs or Part 3 for VTs) modify or supplement the requirements laid out in Part 1.

To ensure new CT and VT designs meet international dielectric, thermal, and mechanical safety margins.

IEC 61869-1 is an indispensable document for the power engineering industry. It establishes the baseline rules for safety, terminology, ratings, and testing that protect both human operators and expensive grid infrastructure. For anyone looking to procure, design, or test instrument transformers, referencing the full, official PDF of IEC 61869-1 is the first step toward compliance and engineering excellence.

If you don't need the full standard text, consider these free resources:

It covers transformers used in AC systems with frequencies ranging from 15 Hz to 100 Hz, typically for voltages above 1 kV, though it also provides the basis for low-voltage applications.

The International Electrotechnical Commission (IEC) addresses this need through the IEC 61869 series. At the core of this series is , which outlines the general requirements for all types of instrument transformers. What is IEC 61869-1?
