Answer / aravind

Because the capacitor is using for powerfactor improvement
and it is regulating the voltage level thatsway we have
getting more current than rated

Answer / arvind

if you are connect capacitor on the secondary side that
means you are correcting the power factor of load side, but
if you put the bank on the primary side then u will notice
the current required will be less.

Answer / anupnaik21

may be due to leading power factor that causes over 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.
