how to calculate the capacitor rating for improving power
factor
Answer Posted / engbri
Another way i use is to take the PF and turn it into an
angular measurement in degrees. using j notation and the
magnitude of the wave you can calculate the size of
resistance, or real component and the size of the inductive
reactance or the -J component. Do this with a simple Polar
to rectangular conversion, if you cant your calculator
probably can. Then making the capacitive reactance equal to
the inductive reactance cancels it as they are oposites.
Then using the formula Xc = 1/2piFc transpose for c which
gives c =1/2piFXc. however as the cpacitor is taken as
ideal and with no resistive component this will never
reduce the PF to zero.
