Why short circuit characteristic of alternator is linear? The short circuit characteristic is linear. The flux density in the machine is very low since the terminal voltage is zero. The air-gap flux is sufficient to produce a voltage to overcome the leakage reactance drop. From these two curves, the synchronous reactance can be found.
Why SCC curve is a straight line? The OCC is a straight line till saturation point. As field current increases, Emf induced increases proportionally (according to emf eqn of synchronous machines). Thus we get a straight line. But after saturation, there is not a direct proportionality relation between field current and Emf.
Which characteristics of an alternator is always linear? The SCC will be linear since the magnetic core does not saturate under short-circuit conditions. The armature effective resistance Ra is often very small and may be neglected in most problems. If this value is included in the analysis, it will typically be provided.
Why SCC is linear for cylindrical pole alternators? However, as the flux density increases, the poles get saturated and the ɸ becomes practically constant. Thus, even we increase the If further, ɸ remains constant and hence, Eg also remains constant. Hence, the O.C.C. curve looks like the B-H characteristic.
