In power systems, a power factor of unity (1.0) indicates that the voltage and current are in phase, meaning all the power is being effectively used for work, with no reactive power. However, in practice, power factors are often less than unity due to the presence of inductive or capacitive loads, which can cause phase differences between voltage and current. Utilities aim to improve power factor to reduce losses and increase efficiency, but achieving a perfect unity power factor is typically not feasible in real-world systems.
