Why current flows in nutral? As per theory there should be
no current in 3 ph explain.
Answer Posted / ashokreddy r
In single phase systems current flows thro the neutral as
it is the return path
In three phase systems w.r.t individual phases there is
neutral current .(Ir0,Iy0,Ib0)
For balanced system Ir0+Iy0+Ib0=0
For unbalanced system Ir0+Iy0+Ib0 not equal to zero

This is reqd for a 1MW Solar power plant..We have 2DC outputs from the solar panels Connected to 2INVERTOR panels.. Output from invertor is 3ph,280v,500kva,50hz.These are connected to individual ACB.This has to be stepped up to 11KV ,1250KVA SYSTEM.Now can I use (1) one more ACBTO GIVE A COMBINED OUTPUT OF 1000KVA,280V & STEP UP THE OUTPUT BY USING a single two winding 3 ph transformer 11kv/1250kva. or (2)use the two outputs and connect to one three winding transformer of above rating..Pls suggestwith details.
