Answer Posted / ramendra shukla
As we know the Relationship of Mech. HP with Elect. KW is-
HP = 0.734 KW
P= VI in KW (let PF is unity or pure resitive load)
First we will get the the Voltage V, and then the current,
C in amps By this we will calculate the Horse power ,HP.
Lets have an example
Q:- A motor is taking the current as 30 amps & the voltage
is having 420 calculate how much HP it have??
ANS :
We know HP =0.734 KW
& P= VI cos@ (let cos @=1 or pure resitive load)
then
P = 30x420x1 KW
= 126 KW
So,
HP =0.734x126 :=92 HP
