Answer Posted / pratik
Since breaker operates in transiant state & it is design to
pass the sub transient current through it.But it is
supposed that if breaker is just about to close & fault
occurs at the same time then breaker will have to close in
that sub transient period & thus amount of arc produce will
be very high.Thus making cap. is very high.

what is through fault?
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.
