Answer / iamdon
Large rated alternators are of rotating field type where as
DC genertors are of rotating armature type.The basic reason
behind different choice of arrangements is governed by
following factors.
INSULATION in the case of alternator and
COMMUTATION in the case of DC generator.
In the case of large alternators, more insulation is
required for large voltage generated in armature
winding.Being armature placed on stator,it is easier to
provide insulation for the stationary armature winding.Also
armature is placed on radially outer side, so we can put
more and more insulation(if required for higher voltage)in
the space avaliable.
In the case of DC generators,AC is generated in the
armature winding which is converted into DC, by means of
mechanical rectifier i.e, commutator.It is convenient to
adopt rotating commutator and fixed brush ararrangement for
collecting DC through brushes.So we need to place armature
winding on the rotor.

What are the different lines and what are the different types of losses occur on them?
how we control automatic generator i'e with to supply (main supply and local generator) when the main supply was break to supply the local supply automatically to begin supplying power.I now this control circuit is the combination of contactor time delay contactor switch and overload relay .but my question is how we combine those component thank you
