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 / 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
