• IEC 60044-series (e.g., IEC 60044-1 for CTs, IEC 60044-2 for VTs).

The IEC 61869-1 standard, titled "Instrument transformers – Part 1: General requirements," serves as the foundational "product-family standard" for the entire IEC 61869 series. It establishes the core principles that apply to all types of instrument transformers—such as current, voltage, and combined units—used in high-voltage applications (>1 kV AC or >1.5 kV DC). 1. Scope and Core Purpose IEC 60044-series (e

4. The 2026 Perspective (As of Today)As of 2026, IEC 61869-1 is the definitive standard for integrating modern instrument transformers into intelligent substations, facilitating high-speed data transmission and enhanced safety in power generation and distribution, as described on iTeh Standards.

Insulation Levels: Provides the criteria for rated insulation levels based on system voltage and environmental conditions.

Once upon a time, electrical substations relied on the IEC 60044 series of standards to guide how instrument transformers—the devices that step down high voltages and currents for safety and measurement—were built. However, as the world moved toward digital substations, "smart grids," and higher-frequency, cleaner energy, the old standards became outdated.
