Answer Posted / stanley electrician
capacitance of the capacitor is mentioned in KVAR.
Formula : KVAR = KW*tan@
FOR tan@, First note the power factor & KW without
connecting capacitor.
The noted power factor is in cos@.Convert the cos@ value in
tan@.
for ex. If power factor is 0.6, KW = 200
cos@ = 0.6
cos-1 (0.6) = 53.1
tan (53.1) = 1.333
200*1.333 = 266.6 KVAR
if you use 266 KVAR capacitor, Then the power factor
improves to unity (1.000).
