Answer / naresh

rating =5*0.7457 =3.7285kw
vol =440v
3phase
current=(3.7285*1000)/(1.732*440*0.85) =5.755A

Answer / meraj

Given: v=440v, 3phase, pf=0.85, hp=5hp I=?

1hp=0.746kw
5hp= 5*0.746 kw = 3.73 kw
now P=3.73kw
for 3phase P=1.73*v*i*pf
I= P/(1.73*V*PF)
I = 3.73*1000/(1.73*440*0.85)
I = 5.76 amps

Answer / siva

power=1.732VIcos Pi
Hp to Kw
5x746=3730

I=3730/1.732*440*cos 0.85
I=4.89 A
