Instrument transformers are devices used to transform high-voltage and high-current electrical signals to lower levels, making them suitable for measurement, protection, and control applications. These transformers are crucial in power systems, allowing for the safe and accurate monitoring of electrical parameters. Instrument transformers are broadly categorized into two types: voltage transformers (VTs) and current transformers (CTs).

It absorbed IEC 61869-6:2016 (low-power instrument transformers), consolidating rules for both traditional and digital sensors. : Specifies standard temperature-rise limits and the impact
This standard acts as a "Product Family Standard," meaning it provides the general framework that must be read in conjunction with specific product standards for various transformer types. It is applicable to instrument transformers used in high-voltage applications where nominal voltages exceed or 1.5 kV DC . It is applicable to instrument transformers used in
