What is the rating of your capacitor bank at your company...

Answer / sharma jiten

The most common method for improving power factor is to add
capacitors banks to the system. Capacitors are attractive
because they're economical and easy to maintain. Not only
that, they have no moving parts, unlike some other devices
used for the same purpose.

When you add a capacitor bank to your system, the capacitor
supplies the reactive power needed by the load. If you size
and select the capacitor bank to compensate to a unity
power factor, it can supply all the reactive power needed
by the load, and no reactive power is demanded from the
utility. If you design the capacitor bank to improve the
power factor to a quantity less than 1.0, the reactive
power supplied by the bank will be its rated kVARs (or
MVARs), while the rest of the reactive power needed by the
load will be supplied by the utility.

Answer / chandru

The addition of capacitance depend upon your power factor.suppose u may get more than 0.97 or unity Pf,u no need to add capacitor.becoz it may act like load

Answer / vinesh

Power factor is only present in the ac power supply systems. In dc there is no usage of power factor terms. Ac supply is having frequency and potential is alternating with respective to time as such the load on the ac power source is of mix like capacitance, resistance and inductance

Capacitance is offered by ug cables and heater and filament lamps offer the resistive loads and hid and fluorescent lamps offers inductance value

Inductive reactance (xl) and capacitive reactance (xc) is counter each other and resultant effect will reflect in ac system in addition to normal resistance. This cumulative resistive effect is called as impedence.

Now power factor is equel to pf = r/z.

Now if we draw a power circle the you know the differnce of kw and kva is made by kvar that is reactive power if we reduce this reactive power then the kva demand and kw i mean apparent power and actual power will became more or less equal. Now power factor that is quality power.

So we can improve the power systems by adding counter reactive power by adding capacitors in kvar ratings.

Apfc panels are best suitable for proper monitoring as static correction will not perform well in massive load centres as failure and degradation of capacitor is hard to find out and rectify.
