I like the answer which is talking about the cu losses and
characterstic of the transformers.
let me drive the answer from differint angle.
let us assume that we told you that, the transformer is 20
MW, and now you want to connect motor of 15 MW to this
transformer, are you able to start this motor from this
transformer before the protection setting trip the circuit
breaker of the transformer?
I don't really know!! because I don't know how much
reactive power in this transformer, in other words, I don't
know how much losses in this transformer, then I can't do
prpoer analisys of the motor starting without knowing the
MVA rating.(which will include active and reactive power)
my advice, please try to do motor starting analysis on ETAP
or Matlap or any electrical softwaer and play with the
reactive power and see the differance and you will be clear
more ^_*
good luck

Please help me regarding my one concern. - During earth pit testing we noticed that the Clean earth pit and dirty earth pit showing continuity (Resistance value - 5ohm) . I want to know that if both earth pit have separate location and there is not internal looping between PIT then why such continuity is showing on it . Because of this issue the field side all earthing point showing short. In PLC panel we are providing two types of earthing cable which is coming from separate earth pit (Clean and Dirty earth pit) because of earth PIT showing short our PLC is not complying spec . please help regarding this issues.
