Answer / anil

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
