WebMay 10, 2024 · The total power factor is calculated as follows: PF Tot = PF × PF THD. PF Tot = 0.906 × 0.898. PF Tot = 0.814. It is important to know the total power factor because it relates to apparent power. Apparent power is used to size the elements of a power distribution system. WebReactive power (KVAR) required by inductive loads increases the amount of apparent power (KVA) in your distribution system (Figure 4). This increase in reactive and apparent power results in a larger angle θ (measured between KW and KVA). Recall that, as θ increases, cosine θ (or power factor) decreases.
