scope:

This Technical Specification defines criteria for assessing the insulation system of stator/rotor windings which are subjected to pulse width modulation (PWM) drives. This Technical Specification applies to stator/rotor windings of single or polyphase AC machines with insulation systems for converter operation.
It describes qualification and type tests on representative samples or on complete machines which verify fitness for operation with voltage source converters.
This specification does not apply to
¨C rotating machines which are only started by converters;
¨C rotating electrical machines with rated voltage ¡Ü 300 V r.m.s.;
¨C electrical equipment and systems for traction.
