Answer / kannu

Inductane of coil is given by l=flux linkage/current
through coil.
As current through coil increases saturation may set in and
corresponding change in flux might be less, this leads to
decrease in inductance of the coil.

Answer / balaji

inductance of coil depends on number of turns of the coil.if
turns vary,resistance will defenitly vary,so current changes
and viceversa

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.
