could any one explain me what power factor and where it is
use ful

Pf is the co sine angle between voltage & current,it depends on kind of load ,if the angle is more gen "ll hv more current(actual +reactive current) un necesserily(kvar),which means same load more current,causes overheating of d/g,in case of comparatively less load over current trip will occur.

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.
