Answer / mohammed hussain a
Power in KVA = (1.732 * V in Volts * I in Amps)/1000*PF
For 3 Phase Supply
Power in KVA = (V in Volts * I in Amps)/1000*PF For 1
Phase Supply
or
KVA = KW/PF

Answer / r.muthu kumar
Killo Watts When KVA is knomw = KVA X Power Factor
Killo Watts 3 Phase = (I X V X 1.73 X P.F.) / 1000
Killo Watts 1 Phase = (I X V X P.F.) / 1000

Answer / parvez ahmed
For 1KW=1.25KVA
So...
PF=.8
1KW
KVA=KW/PF
=1/.8
=1.25KVA

Answer / kanth
actually
kw= vicos$
and
kva= vi
so KW= KVA/Cos$
cos$=KW/KVA
or
KVA=root of (Kw sq +KVAR sq)
| Is This Answer Correct ? | 6 Yes | 1 No |
For 3phase supply
KW= 1.732VIcosQ
KVA=1.732VI
for 1phase supply
KW=VICosQ
KVA=VI
if KW givwn means
KVA=KW/CosQ

Answer / ravinder
AS PER THE PRACTICAL ASPECTS CONSIDERING PF
PRACTICALLY ....FOR 50 HP MOTOR WE HAVE TO TAKE 37.5 KW
(I.E. FOR 100 HP WE ARE TAKING 75 KW)......
