Answer / guest

The current that is passing through winding creates magnetic
flux, some part of the flux links with the core of the
transformer, due to this core experience the magnetic
simulation of electrons and then the electrons will
continuously change the direction due to magnetic field and
some time they align in one particular direction and they
will not change the direction irrespective of continuous
magnetic field, hence we will use the term saturation of
core at that point of time.

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.
