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

\
1kva=1000/1.732*440=1.32A for 3 phase
1kva=1000/240=4.16A for single phase

What is the breakdown voltage?
We are having a 2000KVA DG set. It trips with Over speed and Engne Hot when the mahine is stopped in full speed. How shall I analyse the block load and reverse power.Is the problem related to power factor. The machine which runs on this DG is having all Synchronous motors with incividual Drives.
can you explain the rms value in simple words....
