IEC 34-15:1995 ROTATING ELECTRICAL MACHINES -Part 15: Impulse voltage withstand levels of rotating a.c. machines with form-wound stator coils
1scope
This part of lEC 34 specifies the rated phase-to-earth impulse voltage withstand levelsof rotating a.c. machines having rated voltages from 3 kV to 15 kV inclusive andincorporating form-wound stator coils, together with the test procedures and voltages to beapplied to the main and interturn insulation of sample coils to prove the compliance of themachine.
