Power Factor is defined as the ratio between the Real Power and the Apparent Power in an AC circuit. Real Power represents the net energy transferred to the load over one complete AC cycle, while the Reactive Power represents the fraction that is only temporarily stored by the load. The Real Power is measured and monitored for power consumption, with its associated energy being used to produce mechanical work and heating. Traditionally, the power factor is associated with the cosine of the angle between the real and apparent power components. For simplicity, the apparent power can be represented as the vector sum of the real and reactive power, but in the case of non-sinusoidal periodical signals, a more complex relationship between these components is considered.
