scope:
Applies to single-phase and three-phase oil-immersed power transformers (including auto-transformers), with the exception of certain and special transformers, as defined in the scope of IEC 60076-1. It identifies transformer windings to their highest voltage for equipment Um associated with their corresponding rated insulation levels and details the relevant applicable dielectric tests and minimum external clearances in air between live parts of bushings and to objects at earth potential.
