1 L.Current xL.Volts x1.732 = KVA =
KW = HPX746
1000 PF
1000XEfficiencyxPF
2 L.Current xL.Volts x1.732XEfficiencyXPF =
KVAX1000XEfficiencyXPF = KWx 1000
xEfficiency = HP
746 746 746
When KVA know When KW know
When HP know
3 L.Current = KVAX1000 = KWx
1000 = HPX746
L.VoltsX1.732
L.VoltsX1.732XPF
LVoltageX1.732XEfficiencyXPF

Answer / shanker ganesh
first convert HP to KW (ie)1HP=0.75kw approx. from that u
can got KW valu then by using normal formula ie) kw=root 3
v i cos pi, u calculate KVA.

Answer / raghavendran
1 HP = 746 watts/motor designed PF = motor rating in KVA
for 50 HP motor = kva rating = 50 * 746/.85(say) = 44 KVA

when neutral will carry the current?what could be the magnitude?
i want to ask that as everybody knows that in star connection on star point is called neutral. my question is that why on that poin called neutral. what is the reason behind it. what is the logic behind it. i heared somewhere that on this point all phases current become zero thats why. if this answer is right then prove why on that point is current become zero. if this answer is not right then tell me the right answer. post ur answer here or on my mail address. m.ikram786@yahoo.com m.ikram555@gmail.com. thanks.
why we connect dg neutral with ground?
