HOW TO CALCULATE THE CAPACITOR RANGE FOR LOAD FOR PF
IMPROVEMENT?
EXPLE:FOR 65 HP LOAD HOW TO CALCULATE CAPACITOR RANGE?
Answer Posted / deepakindi1
Boss what if u dont have the table?
let Cos(@1) be the present PF
@1=cos'(@1) (cos inverse)
let Cos(@2) be the desired PF
@2=cos'(@2) (cos inverse)
KVAR required= KW[ tan(@1)-tan(@2)]
for 65 Hp load
KW= 65HP*0.746 = 48.49KW
Considering Preent P.F=0.50
desired pf =0.99
ie cos(@1)=0.5
@1=cos'(0.5)=60
@2=cos'(.99)=8.1
kvar=48.49*[tan(60)-tan(8.1)]
=48.49*[1.732-.142]
=77.08
kvar=77.08
