Specifies standard phase-to-earth and phase-to-phase insulation voltage withstand levels for electrical equipment, other than generators and other rotating machines, as used in a.c. electricity supply systems. Describes the basic principles of insulation coordination, test procedures and insulation voltage withstand levels for highest voltage for equipment above 1 kV in three ranges A, B and C, and introduces probabilistic concepts and a statistical approach to insulation coordination.
