Hello,
I would like to clear out something.Let's say I have the following given:
A 50KW motor,460 Volts,3 phase.It has a power factor of 0.85 and an efficiency of 100%. Ok now let's say we want to raise the power factor to unity, after doing the calculations you will get that we need 30.986 KVAR the required capacitor size.Now here comes my question:
if I want to calculate the capacitance in Farads,which of the following relations should I use?
1-KVAR = V^2/Xc
2-KVAR = (V^2/Xc) x sqrt(3)
I mean when we calculate Q,we used the following
Q(KVARs)=V x I x sqrt(3) x sine(phi),so by substituting V x I by V^2/Xc I should get equation 2,right ?
Thanks to everyone that will contribute.
