Proper Sizing of Power Factor Capacitors
Proper Sizing of Power Factor Capacitors
(OP)
I'm currently performing a power factor correction on a plant, and I've calculated that I need to install 2400 kVAR reactive power correction. I have decided that I would install 5 banks of 500kVAR capacitors. The problem I now face is that I have received quotes on 150kVAR single phase capacitors. I don't know how to apply these single phase capacitors to this problem. Any adive will be helpful.






RE: Proper Sizing of Power Factor Capacitors
What you probably need is four banks of 600 kvar, made up of 200 kvar 1Ø capacitors.
RE: Proper Sizing of Power Factor Capacitors
You add the capacitances to have total capacitance.
Take care of harmonics in the circuit and resonance.

RE: Proper Sizing of Power Factor Capacitors
This allows for greater control of the final power factor, certainly you will need to consider harmonics and the use of detuned capacitor banks ie fitted with rejection reactors.
