Resumen (inglés):
Applies to three-phase synchronous machines of 1 kVA rating and larger with rated frequency of not more than 400 Hz and not less than 15 Hz. An appendix gives unconfirmed test methods for determining synchronous machine quantities.
Notes:
1 -Tests are not applicable to synchronous machines such as permanent magnet field machines, inductor type machines, etc.
2 -They also apply to brushless machines, but certain variations exist and special precautions should be taken.
