The International Electrotechnical Commission (IEC) has established a series of standards for instrument transformers, with IEC 61869-1 being a crucial part of this series. This standard, titled "Instrument transformers - Part 1: General requirements," provides the foundation for the design, testing, and use of instrument transformers in various electrical applications. In this article, we will explore the significance of IEC 61869-1, its contents, and the impact it has on the industry.

Purpose and scope

At the core of this series is , which outlines the general requirements for all types of instrument transformers. Understanding this standard is essential for electrical engineers, manufacturers, and utility operators. 1. What is IEC 61869-1?
