Answer / ram t shelke

Techanically speaking , Generator is a DC machine i.e an
machine used to supply DC power.but you are saying that it
is a 3phase machine . so you might be talking about
alternator.
if you know the value of generator current , it can be
expressed in terms of KW provided one should know the
terminal or O/P voltage of generator.use following equation
for the required convertion.

KW = 3* TERMINAL VOLTAGE per phase (V) * RATED CURRENT
per phase (A) * power factor/1000

On the other hand , if you know KW out put, one can
calculate corresponding current by following equation

current per phase(A) = kw rating*1000/ 3* voltage per phase
(V)* power factor
