Phasor Diagram of a Cylindrical Rotor Alternator

The load angle δ is between

Phasor diagram below is best describing the

The leakage reactance can be determined with lesser accuracy by using Potier triangle.

From the OCC and SCC curves, what does the intercept BC represent?

From the OCC and SCC curves, what does the intercept AB represent?

The flux addition is due to
(i) sinusoidal distribution of mmfs
(ii) zero relative velocity between two mmfs
(iii) spatial distribution of three phases by 120°

The internal power factor angle Ψ is between

The short circuit characteristic of alternator is a straight line due to

Potier method is very accurate due to

If the resultant flux will not be in phase with the resultant mmf F_r. This is due to
