Answer / guest

First generator need to connect ,while second generator
nuetral kept open

Answer / rajesh anne

any one of the generator neutral need to be grounded.if it
is multiple generators also one generator neutal must need
to be grounded because the unbalnce currents will pass
through the neutral while it was running in parallel.

Answer / amrinder

please give clear answer.....waiting..

Answer / muninanjappa

First Generator must be grounded and next generator neutral
must be left open works as floating neutral.
Both Alternator neutrals should not be earthed while running
in parallel

Answer / b madhu sudhan reddy

when two genarators are conected in parllel then it must
satisfy the synchronisam i.e it must satisfys certain
conditions.suppose when it falls to out of synchronisam
then there is chance of occuring the fault i.e there is a
chance for circulating high currents,at that particular
situtation the nutral will help for flowing that currents
to ground&it also protect the system when the lightning is
occur

Answer / guest

the neutral is grounded

Answer / guest

earth

Answer / sreeraj n

the generator ,which we first connect to bus ,that generator nuetral need to connect to load ,other generators nuetral kept open

Answer / mallikarjuna reddy

I Hope we have to connect the both neutrals(individual
alternators)to the earth.if fault occurs when that
synchronism fails unbalance currents will flow through this
neutarl to ground.

Answer / b.ramesh babu

when the generator satisfing the parallesm conditions then
the neutral is grounded because when when the parellelism
conds are not satisfied then the circulating currents are
generated which become one become motor and other become
generator..........so d circulatind currents are flow to
the grounded..
