Defines criteria for assessing the insulation system of stator/rotor windings which are subjected to pulse width modulation drives. Applies to stator/rotor windings of single or polyphase AC machines with insulation systems for converter operation. Describes qualification and type tests on representative samples or on complete machines which verify fitness for operation with voltage source converters.
