ZPfC (zero power fact or characteristic) of a synchronous generator is obtained by performing
-
- generator is loaded to give varying zero pf lagging current while its excitation is adjusted to give the rated terminal voltage.
- generator is loaded to give varying zero pf leading current while its excitation is adjusted to give the rated terminal voltage.
- generator is loaded to give rated zero pf leading current and its excitation is adjusted to vary the terminal voltage
- generator is loaded to give rated zero pf lagging current and its excitation is adjusted to vary the terminal voltage.
