Answer / kenn

kw is your true power,kva is your apparent power ,and kvar
is wasted or watt less power

Answer / ekanadam rathod

kvar reactive power (kvar)
kw ia active power, kva is apparent power kw and kva
depends on power fator pf=kw/kva to maintain power factor
unity we should inject to the lone kavr to compansate unity
power factor
for exmample if power factor is unity then the kw=kva
kw=4, kva=4 so 4/4=1 this case kw and kva same
if pf =0.98 then the 0.98=4/4 then the kw and kva will be
different

Answer / shiva prasad

P= POWER
P= V X I X COS@ IN AC
KW = P X 1000
KW= KILO WATT

KVA= IT IS NOTHING BUT KW

KVAR= V X I X SIN@ IN AC

KW= KVA X PF
