IEC 61869 is an international standard for instrument transformers, which are used to measure voltage and current in power systems. The standard provides specifications for the design, testing, and operation of instrument transformers, ensuring accurate and reliable measurements. In this post, we'll explore the IEC 61869 standard and provide an overview of its contents.

IEC 61869 is a standard published by the International Electrotechnical Commission (IEC) that defines the requirements for instrument transformers used in power systems. The standard covers voltage transformers (VTs) and current transformers (CTs), which are used to step down high voltage and current levels to values that can be safely measured by metering and protection devices.
