E.M.F. equation of an elementary
alternator three phase
Let us
assume that this generator has an armature winding consisting of a total number
of full pitched concentrated coils C, each coil having a given number of turns Nc. Then the total number of
turns in any given phase of a 3-phase generator armature is
Voltage
equation per phase will be similar in to the single phase alternator
The value
of line voltage will be different from phase voltage in case of star connected
generator. The line value of the emf in case of three phase alternator
connected in star will be-
The value
of line voltage will be same with phase voltage in case of delta connected
generator. The line value of the emf in case of three phase alternator
connected in delta will be-
