The standard document serves as the foundational, global framework governing the general requirements for high-voltage instrument transformers . Developed by Technical Committee 38 (TC 38) of the International Electrotechnical Commission, this standard replaced the legacy IEC 60044 series. It functions as a product-family baseline. Every specific type of transformer—whether it is a conventional current transformer, inductive voltage transformer, or electronic low-power alternative—must comply with this document in tandem with its respective product-specific sub-standard. : Defines operation limits for temperature
