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

Answer / jim
p=vicos0
p=5*0.746
=3.73kw
i=3.73/(440*0.85)=9.973amps

When batteries are connected in series the voltage increases but the current remains unchanged, how can this be? When you consider ohm's law. i.e. If voltage increases, current increases, providing resistance remains the same.

I have carried out wiring for lighting in a shed in Industrial area which contains Metal halide lamps & have balanced in 3ph.Now when we put all the lines on in the daytime the current taken at 3phases at MCB comes to be equal i.e.28,29,28Amps respectively but in the night time i.e between 7p.m.to 11p.m. at the same MCb the current is 52,59,62Amp, though I have fit 63A MCB it is tripping in the above period.What may be the reason.? Note: This industry is located in industrial area where majority of steel ingot manufacturing plants are there. Whether this may be due to harmonic? what should I do to overcome above problem.pl suggest urgently.
