Answer / raji g

current transformer usually used to measure the high amount
of current.using normal ammeter we can't measure the high
current in the range of kilo amps. so CT is used here

and

potential transformer also used to measure the high amount
of voltage in starting from kilo volt

Answer / guest

CT for masuring of current
PT for masuring of voltage

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.
