Power factor is the key factor to evaluate how effectively electric power in a power system is being used. If the power factor is high (unity), then the effectiveness of the use of electric power in a power system is more. As the power factor reduces, the less effectively electric power is being used in a power system. There are different reasons due to which the power factor is being reduced and to improve power factor there are different power factor correction methods. Efficient and typically used power factor correction method utilizes capacitors for power factor improvement. But primarily, we must know what power factor is. Power factor can be defined as the ratio of active power to the apparent power. Generally, it is called the cosine of the angle between the voltage and current. Why do we use the cosine of the angle between voltage and current? This is because to consider the power triangle derived from the phasor diagram of voltage/current. The angle between load curr...
