Power Factor Correction
Depending on the nature of electrical loads considerable savings in electricity bills can be achieved by correcting the power factor. The active power of a load is drawn (and paid for) from the supply is measured in kilowatts (kW). The apparent power of the load is the multiple of Current and Voltage (kVA). The ratio of the active power (kW) to the apparent power (kVA) is known as the power factor and referred to as cos f. In addition to the kilowatts per hour consumed, a charge is also made by the supply
authority for the maximum kVAr demand on the supply. If the maximum kVAr can be reduced considerable savings can be made.
This is achieved by connecting suitable sized capacitors to the supply compensating the reactive component of the load, reducing cos f closer to unity (1.0). The nearer cos f is to unity the less reactive power is drawn and the greater the savings on the utility bills. However in practice it is often uneconomic to improve the power factor greater than 0.9 as the size of the capacitors would be extremely large and the cost would outweigh any utility saving. Power factor correction can be supplied as separate units or fitted to our EM range of voltage stabilisers and power conditioners.
This option can be in the form of a fixed capacitor bank, suitable for applications where the load and power factor is fixed and is not likely to change. Alternately the stabiliser can be fitted with a power factor control system to automatically vary the correction capacitance in pre-set steps to ensure optimum power factor improvement irrespective of load variations.
To enable us to calculate your requirements we will require the following information:-

To enable us to calculate your requirements we will require the following information:-
The existing power factor of the load (cos f1)
Rating of the load (kW)
Operating voltage
The required power factor after improvement (cos f2)
Type of correction fixed or variable.
Improvement of power factor will result in a reduction in the overall cost of electricity bills.
