What is Power Factor ?

Power Factor is the ratio between KW and KVA drawn by an electrical load where the KW is the actual power and KVA is the apparent power. It is a measure of how effectively the current is being converted into useful work output and more particularly power factor is a good indicator of the effect of the current on the efficiency of the power system. A load with results in the most efficient loading of the supply. Low PF is generally the result of an inductive load such as an induction motor, Power transformer, lighting ballasts, welder or induction furnace. A low power factor due to an inductive load can be improved by the addition of power factor correction panel.

Technical Explanation

Total power (KVA) consist of real power KW (Power consumed in Phase) and Reactive Power kVAr ( Power consumed out of Phase).
The Power Factor is ratio between real power and total power,
If load is running for H hours.
Then Total Power = kVAr, Real Power + Kwh, Power Factor = Kwh / kVA.
This is the method used by energy meter.

How to Improve Power Factor ?

Capacitive Power Factor correction provides capacitive current to the circuit due to which magnetizing component of load current is cancelled ( as shown in fig. 1) and thereby the power factor is improved.

Benefits of Improved Power Factor

* Removal of Low power factor penalties.
* Reduction in Demand Charges and core losses.
* Decrease I2R Losses 4 times.
* Reduction in electrical breakdown.
* Saving on electric bills.
* Reduced CARBON Emission.
* Improvement of line voltage.
* Surge Suppression.

How To Improve Power Factor Automatic ?

In automatic control, APFC Relay keeps on sensing the power factor all the time and gives suitable signals to contactors connected to the different value capacitors. By fine tuning of relay parameters & load balancing, Unity power factor can be achieved easily.
