How to Convert horsepower to kva? what is the three phase formula? explain me if u can Example..i..

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.
