Answer Posted / pillay
It depends where the neutral is in
open condition.
when all three phases are loaded with
single phase load and the main neutral
is in open condition than the voltage
across the load will vary according to
the load and the voltage can be as high
as phase to phase voltage thus resulting
in damage to electrical equipments, but
if they are loaded symmetrical than the
phase currents are balanced internally
and the voltage across the phases are balanced.

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.
