Sudden Short Circuit of an Alternator | Power System | Electrical Engineering
In abnormal operation, the alternator may be subjected to transient conditions which cannot be explained from steady-state theory. These transients may occur from- (i) Switching (ii) Sudden changes of load, (iii) Sudden short circuit (either line-to-line or line-to-neutral or from a symmetrical short circuit). These short circuits may develop severe mechanical stresses on the armature coils and their end turns [...]
