2 Diesel Generators 900KVA connected to the bus bar for
essential load as an alternative for power taken from
11/440V 3KVA Transformer supplying this bus bar. my
question here is in the event of power failure on 11KV side
can I feed the power to 11 KV bus by using the same
transformer as reverse feed, what will be the inrush
current???

Answer Posted / joy

Your generator will be damaged. The reason being
that the transformer impedance as well as
impedeance of the entire 11kv side will be loaded
on the generator. Besides the inrush current which
the transformer will take when you charge it. This
will lead to the dropping of pf of the generator,
leading to the heating of its windings. Also you
have to make sure there are no chances of the
"normal" 11kv source being re applied when the
generator is being used to charge the 11kv side. Or
else the generator will experience a shearing of
its rotor.
