how many amps in 1 KVA? V=440v, PF=0.8 and FREQ=50Hz
Answers were Sorted based on User's Feedback
Answer / guest
if it is 3 phase
KVA=1.732*V*A
1000=1.732*440*A
A=1.31A
for 1 phase
KVA=V*A
1000=440*A
A=2.27A

Answer / niti
If consider Is in three phase circuit
A=kva*1000/v*1.732
therefore
=1*1000/440*1.732
=1.31A
If Consider is in Single phase circuit
A=1*1000/V
=1*1000*/440
=2.27A

Answer / fazal
Amps = KVA/1.732*V*p.f
= 1*1000/(1.732*440*0.8)
=1.640 Amps

Answer / pearl ganesh
kva=1.732*v*I
I=kva*1000/1.732*440
I=1*1000/1.732*440
I=1.31 Amps

Answer / golak bihari naik
For 3-Ph system
KVA(Apparent Power)=1.732*V*I
I=(KVA/1.732*V)*1000
I=(1/1.732*440)*1000
=1.31 A
For a 1-Ph system
KVA=V*I
I=(1/440)*1000
=2.27 A

Answer / anil
when kva given PF not to consider because formula to find
current is
1)When KVA know
L.Current= KVAX1000/L.VoltsX1.732
2)when kw knows
L.Current= KWx 1000 /L.VoltsX1.732XPF
3)when HP knows
L.Current= HPx746/L.VoltsX1.732XPFxefficeincy
PF effects kw , that is reason our power unit measuring is
kwh

Dear Friends, Need your help for connecting APFC panel, Quotation : I have 2 No’s 1000 KVA Transformers, both transformers are having separate APFC panels, ( Tr-1,400KVAR, TR-2,450 KVAR) Now I want to stop One transformer, present load is 650Amps, Max, So One transformer is enough, I have switched OFF TR-1, but PF is not maintaining properly, its 0.5, So now I want to connect TR-2 APFC also in TR-1 Loads, Can any one answer for my Quotation with drawing, how to connect TR-2 APFC panel in TR-1 Loads,
