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

Two alternators say 1 & 2 are poised to parallel operation. But at the time of paralleing alternator 2 gets out of the system by tripping Earth fault relay. Please send me reply why this is happening?

Here iam a question with SYNCHRONIZATION PANNEL related issue, as i want to design a SYNC.pannel board iam giving the 2 nos of 1MVA Generators to sync pannel , then what wil be the out put of the sync pannel, whether it wil be one cable coems from the sync panel or two cables.. as iam using two transformers to meet my load demand, so pls clear me whether two cables comes from sync panel to connect to transformers or only one cable
