En 61869-2 -

This standard is part of the IEC 61869 series, which replaced the older IEC 60044 series. EN 61869-2 specifically covers inductive (electromagnetic) CTs. Electronic or low-power CTs are covered by other parts (e.g., EN 61869-6 for LPITs).

Always specify CTs by referencing EN 61869-2 including accuracy class, rated burden, ALF (for protection), and FS (for metering). Avoid relying on superseded 60044-1 standards for new equipment.
