what's the reson that,Load is not same on VFD I/P and O/P
Side.whenever DOL condition load is same I/P and O/P side.
Answer Posted / sindhejs
We know that Power out=Torque*speed in rps.
Since in DOL condition there is no speed changing means no
change in power out,while in VFD there will be speed
changing using the frequency control,so the power out
changes from power input in VFD(Assuming that torque is
constant).

I have a current transformer with 1 main reading meter with transformer outside the building and a control panel having 5 CT reading meters with black round coils inside the building. I want to know, A) when current pass through the Transformers, will the current be reduced or be the same and after that B) when current pass through the CT meters with black round coils, will the current be reduced or be the same. C) in the above process will the reading of the main meter be same or different, from the total reading of all the 5 CT meters.
