Is there any calculation to find unknwon(unferroled) phases R Y B in alternator,3 phase motor anybody shoot my problem.
how can we notice this is the respective phase?

Answer Posted / adk

Maximum This kind of unferroled problem will be faced in
rewinded motors & it can be identified by no of ties tied
for winding at near terminal box in a motor & can be noted
as RYB with that identification.

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.
