Couldn't think of anything else to call it...
The question is about effiency of motors in relationship to voltage,
I have a Machine shop, 440V service. Delta.
440V, it's an old dry 600Kva outback.
Most of what they run require 480 or 230.
The voltage is currently 424 on the secondary.Primary 4160.
This is below the 10% margin.
Now the question.......
Can you determine, without including replacement costs or labor, how more efiecent will the motors run? 10%, 25%.
Line losses could be calculated, but the actual effiency would have to increase with the proper voltage.
Am I close?????
Dnk..........
