if we convert watt into kva,which one formula use by us,pls tell me?..

Answer / k.suresh

in 3 phase system,

kw = 1.732*v*I*pf

where kva = 1.732*v*I

from the above 2 formulas,we can convert watts to kva

Answer / jyotirmaya

For 3 Phase Supply
KVA = Watt/ (1.732 x p.f.x 1000)

For 1 Phase Supply
KVA = Watt/(p.f. x 1000)

Answer / ashish umrao

kw=v.i.cos*

kva=v.i.

cos*=kw/kva=kw/cos*=kva proved

if we convert watt into kva,which one formula use by us,pls tell me?..

Answer / nidhi

formula
V*I (Cos)=KW= (V*I*P.F.)
but KVA=V*I/1000
SO
KW=KVA* P.F.
where P.F.=Cos (angle between V&I)
