guys the problem is that my dad recently got the tube well's pump's motor replaced with a 30HP motor as suggested by an electrician because the old motor, that had 20HP rated output, got burnt thrice due to low voltage supplied to our farm. Now he is asking me to find a relation between the power consumed and the rated output of a motor in order to find the extra power consumed by the bigger motor... please help me with this..
And one thing more, would the new motor be able to bear the pump's load in case of low voltage from the feeder without getting burnt?? And is that an economical thing to do??
P.S. i'm really bad at electrical stuff so plz be very elaborate in ur replies.
