Answer / kalaianbu

In practical there is no dc generator.Induced emf in an
any generator is always ac,but by using commutator we are
converting ac in to unidirectional supply.So the dynamo is
an electrical equipment which consists of commutator and it
gives unidirectional curent[not perfect DC]. The another
name of the dynamo is called as DC GENERATOR.
Alternator is an electrical equipment which dont have
commutator arrangement and it gives ac supply.

the names independent of the size .

Answer / ranga

A dynamo is a small size dc generator which varies with
load whereas an alternator is a synchronous generator
having a constant speed of rotation independent of load.

Answer / kalai

NOT PERFECT DC means the dc generater give unidirectional
current its like as the ouput of full wave rectifier.but
the DC supply have zero freq.

Answer / binay agarwal

i wd like to say to "ranga" that, its not necessary that
alternator is independent of load,
in generator side ,there
is two mode- 1st is speed mode,
another- load mode.
in speed mode, at constant input, speed is fixed,
in load mode, load is constant at fixed input.
rest of all is true.

Hai Kalai Anbu

Not perfect DC means what?

Answer / subash konar

Dynamo converts mechanical energy to electrical
energy.Alternator converts direct current to alternating
current.

can we use ps class in combination with protection class in differential protection and over current protection.
