Which one of the following method gives more accurate result for determination of voltage regulation of an alternator?
Potier triangle or ZPF method
Potier triangle or ZPF method gives more accurate result for determination of voltage regulation of an alternator. In Potier Triangle or ZPF method, voltage quantities are calculated on emf basis and mmf quantities are calculated on mmf basis. Therefore, ZPF method is most accurate among all these four methods for determination of voltage regulation of an alternator.
Alternator operates on the principles of
If the prime mover of an alternator supplying load to an infinite bus is suddenly shutdown, then it will
