This part acts as a "mother standard," meaning it applies to all other parts in the IEC 61869 series (e.g., IEC 61869-2 for CTs, IEC 61869-3 for VTs) unless specific exceptions are stated in those parts. Key Components of the Standard:

Insulation levels, rated frequencies, and thermal current limitations.
