We have 5 Distribution sections with variable loads&We have
3 Gensets(500kva,380kva&250kva) our total load is between
400kva to 600kva. so how could we connect 3gensets.
after parallaing two generators current is shooting up in
both the generators.for ex: load is 400 kw..after paralling
and load sharing current in running gen is approx 900 amps
and incoming is 750 amps which is too high when trying
toshift the load current in incoming gen is coming more
than 1300 amps and both getting tripped and making
blackout..
