What is the rating of your capacitor bank at your company.
Answer Posted / 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.
