There are various advantages to using power factor adjustment. Decreased demand charges on your power system, higher load carrying capacities in existing circuits, and overall reduced power system losses are just a few of the advantages. And the advantages of power factor correction adjustment aren’t confined to the financial sheet; it also has significant environmental benefits, implying that your organisation is minimising its carbon footprint and benefiting the environment.
Most electric utility providers charge for maximum metered demand depending on whichever is greater: the highest registered demand in kilowatts (KW metre) or a percentage of the highest registered demand in KVA (KVA metre). The proportion of the observed KVA will be much more than the KW requirement if the power factor is low. As a result, improving the power factor through power factor correction lowers the demand charge, lowering your electricity cost.
Reactive current is required by loads that consume reactive power. Installing power factor correction capacitors near inductive loads at the end of existing circuits decreases the current carried by each circuit. When more capacity is required for additional machinery or equipment, the reduced current flow caused by increased power factor may allow the circuit to carry new loads, reducing the expense of expanding the distribution network and saving your organisation thousands of dollars in needless upgrade expenditures. In addition, the lower current flow minimises the circuit’s resistive losses.
For a given load, a lower power factor results in a larger current flow. The voltage drop in the wire increases as the line current increases, resulting in a lower voltage at the equipment. The voltage drop in the conductor is minimised with a higher power factor, which improves the voltage at the equipment. Although the financial advantage of reduced conductor loss is rarely enough to warrant the installation of capacitors, it might be an appealing extra benefit in some cases, particularly in older facilities with lengthy feeders or in field pumping operations. The losses in system conductors are proportional to the current squared, and as the current is reduced in direct proportion to the improvement in power factor, the losses are inversely proportional to the square of the power factor.
By reducing the demand charge on your power system through power factor adjustment, your business is placing less burden on the electrical grid and thereby lowering its carbon impact. This reduced demand on the energy grid can result in hundreds of tonnes of carbon reduction over time, all owing to the increased electrical efficiency of your power system via power factor adjustment. For a given load, a lower power factor results in a larger current flow. The voltage drop in the wire increases as the line current increases, resulting in a lower voltage at the equipment. The voltage drop in the conductor is minimised with a higher power factor, which improves the voltage at the equipment. Although the financial return from reduced conductor loss is inadequate to justify the installation of capacitors on its own, it is occasionally an appealing extra advantage, particularly in older plants with lengthy feeders or in field pumping operations.
