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

The internal power factor angle Ψ is between

Phasor diagram below is best describing the

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

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

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

The load angle δ is between

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

Potier method is very accurate due to
