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

Dear Friends, I have a 500KVA transformer supplying whole factory having 3 phase and single phase mixed loads. Power room has ammeters connected via CTs for individual phase. Now I know that readings shown on meter for each phase say R,Y and B are line currents. But when I want to know the total on transformer do I need to add the currents of all three phases readings shown on meter or value for anyone phase will give me the correct power load on transformer for that point of time. 2. If ammeter shows unbalanced readings for R,Y, B phases say 150, 250 and 300 respectively so can I assume that 150A i.e average of 3 will be the 3phase load currents and remaining will be 1phase currents. Please clarify my doubt.
while we select CT, why the CT ratio is divided by 5?? ex:250/5,15VA,CLASS-1 CT.Why it is divided by 5??Help me please
