Answer Posted / bharat
In DC motors, Voltage equation is V=Eb-IaRa
V = Terminal voltage
Eb = Back emf in Motor
Ia = Armature current
Ra = Aramture resistance
At starting, Eb is zero. Therefore, V=IaRa
Ia = V/Ra where Ra is very less like 0.01ohm.
i.e, Ia will become enoromously increased.

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.
