Learn MoreA capacitor helps to improve the power factor by relieving the supply line of the reactive power. The capacitor achieves this by storing the magnetic reversal energy. Figure 7 shows an inductive load with a power factor correction capacitor. Figure 8 above illustrates the improvement in power factor when the capacitor is added to the circuit.
Therefore, the primary effect of the series capacitor is to minimize, or even suppress, the voltage drop caused by the inductive reactance in the circuit. At times, a series capacitor can even be considered as a voltage regulator that provides for a voltage boost that is proportional to the magnitude and power factor of the through current.
Although power factor correction capacitors can considerably reduce the burden caused by an inductive load on the supply, they do not affect the operation of the load. By neutralising the magnetic current, capacitors help to cut losses in the electrical distribution system and reduce electricity bills.
The power factor typically ranges from 0 to 1. The closer the value is to 1, the higher the power usage efficiency. In direct current circuits (purely resistive loads), the current waveform and voltage waveform are in phase with each other, resulting in a phase difference of 0 degrees. Therefore, the power factor is as follows:
To further improve the power factor, adding a power factor correction capacitor to the coil can reduce the reactive power consumed by the coil, thereby reducing the total current consumption. Understanding power factor characteristics is essential for maximizing the efficiency of power systems.
As shown in Figure 4, by the application of a shunt capacitor to a feeder, the magnitude of the source current can be reduced, the power factor can be improved, and consequently, the voltage drop between the sending end and the load is also reduced. However, shunt capacitors do not affect current or power factor beyond their point of application.
